By the time most people stumble onto a really good course, the show has moved on and access is closed. The Aquaponics Design Course, taught by Australian Aquaponics kit builder and teacher Murray Hallam is such a fine course.

Ecofilms shoots and edits Murray’s training videos and we’ve partnered with Murray to bring you the best 8-Week structured aquaponics course on the planet. We actually visit farms all over the world and get the nitty-gritty details and facts that most people are unaware of in successfully managing and implementing a profitable farm enterprise.

How profitable you may ask? Well, one farm we visited in South Korea (Manna CEA) was housed in over six large one-acre sized greenhouses. The fish tanks were above ground swimming pools! It was huge! The young partners studied Aquaponics doing one of  Murray’s training courses near Brisbane Australia, went back to South Korea, did a crowd-funder and leased a greenhouse and are now harvesting 200,000 greens per month, employing over 60 people and turning over US$1.2m per month! That’s just through their Online orders.

They are also not just producing edible greens and lettuce, but selling value-added products – sauces and relishes and even conducting research into the organic greens for the cosmetic industry. Yes, believe it or not, high quality organic produce from Aquaponics suggests some of the greens are suitable for skin care cosmetics.

So the course has visited many countries from the Middle-East, India, Hong-Kong, Hawaii to the USA.

Murray stresses that the course is for anyone, even a raw beginner wanting a small home system for their family needs. That’s where the course starts. The very basics in Week-1 are shown in a series of video lessons where students get to participate and ask questions from Murray on a weekly basis. Each week Murray has a Q and A session in a live webinar event. There are a weekly course handouts in pdf format as well as DIY project plans for those wishing to build their own system. Murray’s course caters for people wishing to expand and build a larger system for schools or those interested in setting up a community group to grow plants and fish.

Every detail is discussed and shared in weekly video format lessons that are lavishly illustrated in animation, with charts, plans, graphs and downloadable spreadsheets with facts, formulas and recommendations designed for Aquaponics success.

Each week the course expands on this knowledge and covers essential details in pH chemistry and fish health. The middle of the course advances to plant health. What supplements and additives do you need to add to your system to grow robust plants bursting with health?

The course is tailor made for those seeking to expand their system into commercial farming. Most of Murray’s students have done just that and this course visits those farms around the world in cold, hot and mild climates and gets feedback from real farmers with skin in the game, generously sharing their hard won knowledge.

Certification is also offered for those people who submit a design exercise plan for Murray to critique. Feedback from students who have done the course has been very well praised. A selection of the hundreds of testimonials can be found on Murray’s website here.

Testimonials

Shadi I. Syria 22 Feb 2018 – Thank you for your great efforts. You were my friend and my assistant in the years of siege. For three consecutive years, my family and i were trapped in our town in Syria and your videos were our only help in making our food and saving us from starvation. thanx again

Regina M., Toronto, Canada, 19 Feb 2018 – I would like to say thank you for this awesome program. The way in which you teach is easy to understand and very well done. I wanted to learn about aquaponics so that I can install a system at the boys and girls club I teach at. Well, just last week the children and I installed a small system in the classroom. We are now cycling the system!

Jason O., United States, 2 Feb 2018 –Thank you Murray for offering this course. I have enrolled in multiple courses and feel that this course is the best by far and most informative. thank you again for this opportunity, I look forward to taking this course again in the future.

Shailesh P., United States, 1 Feb 2018 – This course is absolutely perfect. It covers beginner to advance topics and puts together all the knowledge one needs in a single place. Murray is a great instructor and very personable. I enjoyed it tremendously and have recommended it to my friends.

Stuart D., Australia, 31 Jan 2018 – Murray is very inspiring. Worth while doing. Information packed.

Richard D., France, 17 Jan 2018 – I recommend Murray Hallam’s Aquaponics design course to everyone who would like to set up an aquaponics system, whether it’s for home only or commercial purpose. Murray has great experience in aquaponics, and shows it in his videos. He has countless systems that he started and where he makes experiments (the best would be the 4m-tall papaya tree) and you get to see them during the course. What is also important and impressive is the many interviews and visits of farmers and farms all around the world. It proves the sustainability of aquaponics and it is not just backyard experience. By the way, I love Murray’s sense of humor. It makes the course fun and not boring at all. So if you look for an aquaponics course, don’t hesitate and take Murray’s. You’ll be amazed at what you will learn, even if you think your English is not good enough or you don’t understand his Aussy accent: he has sub-titles for all videos!

Julie L., United Kingdom, 16 Jan 2018 – Murray Hallam has always been the go to guy for a practical down to earth approach and extensive knowledge about aquaponics. His straight forward teaching method is a joy and the lack of hype really appeals to me.

Petre J., Germany, 15 Jan 2018 – The Aquaponics Design System course is the best course I ever attended to in my entire life. This is the course where you really learn everything about plants and fishes working together one for each other in order to feed you and many others. Thank you Sir Murray!

Students from over 48 different countries have signup for the course which is announced every three months and is always fully booked out that week. The course is then closed to new admissions as that intake of students begin to spend the next 8-Weeks studying the course material and planning and building their own system under Murray’s helpful advice.

If you’re interested in becoming a student, look out for the next Online course which will be posted on the official Aquaponics Design Course website. Or check out the official Course Facebook page which is regularly updated with Aquaponics knowledge.

One of the great things about running an Aquaponics system is how robust and healthy your plants should look. Yet, we’ve seen a number of systems where the plants looks stunted and wilted with that characteristic mottled mineral deficient appearance on the leaves that reveals the plant is actually NOT healthy and is in fact struggling to survive. You’d be amazed how many people do not notice that their plants are in poor condition.

Poor Nutrient Deficient plants

This is where a good aquaponics design course will come in handy especially if you wish to grow nutrient rich healthy plants for yourself or to sell to others.

Our Aquaponics Design Course will help you identify problems before they occur. We’ve had a number of people who have created their own system tell us how much knowledge they’ve gained from participating in our course and how it has improved their skill levels in becoming proficient farmers.

We cover the very basics from beginning to end and give you all the tools to build a small home system, a larger system with IBC tote tanks or a small farm family system that you can build – right up to giving you the confidence to construct a commercial farm.

Build the System that’s right for you

These commercial systems were all built by students of Murray Hallam so you can be sure the knowledge presented is extremely accurate. We also cover over 5 different aquaponic farms around the world in different climate zones, so you can be confident you are getting a solid education based on different parameters and different fish stocks. Knowing how successful farms do it, will help you calibrate your own system to suit.

This is our fifth course which starts this Sunday 11th March 2018.

The course is an event. We take you through weekly videos presented by Murray Hallam. You need to devote about three hours a week of your time to view each week’s group of lessons. Most lessons are around 8 to 10 minutes in duration. The longest is 20 minutes. They can be viewed on your cell phone, ipad or computer and usually explain a key concept that you need to understand. All the lessons are subtitled in English so you won’t miss a thing in instruction. Lessons are organised over eight weeks and towards the end of the course you can gain a Certificate in Aquaponics if you successfully submit a design for assessment.
So look out for it.
The Course opens at 9 am (AEST time) Sunday 11th March only at aquaponicsdesigncourse.com and will end early or as soon as the course is fully subscribed.

Our aquaponics system is now approaching its fourth year since we installed it here at Ecofilms and over the years a multitude of vegetables and fish have gone through it.

Countless tomatoes, cucumbers, herbs, lettuce and fish have been grown from seed and fingerling, right out to maturity to ultimately grace our dinner plate. In fact we’ve kept some of the older fish, just to see how they would fare. Like an old friend, this 2lb barramundi (pictured) grew accustomed to being fed and would eagerly hang out near the entry to the hatch to be the first to  feed on the fish pellets each morning.

Whilst the younger fish would slap the water with vigor and determined zeal, this older fish grew relaxed over the year and would slurp the feed down with a quiet measured grace .

Sadly though the time has come to keep the system in balance and the water quality clean so it meant a few of the old timers days were numbered.

Its sad in a way because you do get attached to your fish a bit and like to see them swim about majestically. They hardly know their number is up when D-day approaches.

Out comes the net. The fish is not bothered or stressed at all as it is edged inside and then its lifted out and quickly dispatched humanely. In fact there is very little stress and struggle for the fish. This barramundi just swam right into the net and was lifted right out of the tank in seconds. Catching fish in your backyard never looked so easy!

Most people find it incredible to be able to grow fish in the backyard like this. For many its the reason they become interested in Aquaponics in the first place.

This 2lb Barramundi fish took less than two seconds to harvest out of the fish tank.

Fishing is never easier than this, but you have to harvest the fish and eat them or give them away.”

But growing fish is not the reason we do it at all. The fish are the nutrient providers. They are the motors that drive the system. That power the feed for the vegetables. The problem is when we have too many “motors” powering the system, that it can get out of balance, providing too much nutrient and turning a valuable resource into a pollutant.

Hence the need to cull some of the  older fish and bring the system back into balance. Fishing is never easier than this, but you have to harvest the fish and eat them or give them away. Its a wonderful way to have the BBQ blazing away and the aquaponics tank nearby and selecting your fish is easy as pie. We’ve had catfish, jade perch and barramundi grown in our system and all live quite happily together and all eat the same feed.

So what do the fish taste like? Do they have any off flavours? Not at all. They taste like – well,  just like fish you’d buy in the local store. Even better because they are fresh and clean. No chemicals or dangerous metals in their flesh. Clean wholesome food grown at home gives you a great feeling of success too.

Barramundi have a reputation as a fine dining fish, but we prefer Jade Perch. Its a slightly oilier fish and tends to have a stronger flavour. It all comes down to personal preferences.

How hard is it to keep fish in an Aquaponics system?

Over the four years, we’ve found the system seems to mature with little effort needed on our part to maintain the system.

You do need to feed the fish regularly but if they miss out for a few days, they can survive quite nicely without much effort. A mature aquaponics system only needs to be inspected occasionally.

I give the pump a clean once a fortnight for any obstruction to the water intake vents. The sides of the tank have a slime coating now. Yes, there is a thin coating of algae on the sides of the tank. I give it a clean once or twice a year, seeing it more like a protective natural barrier rather than an air depleting system, because algae will take some precious oxygen out of your water, but we haven’t seen the fish suffer for lack of air..

Clean water well filtered is probably the main priority with enough oxygen to keep the fish alive. Keeping a standby pump in the garage is also a good idea but we are still using our first  60 Watt pump and it hasn’t missed a beat.

A separate 8 Watt four-outlet aquarium  air pump will help supplement the needs to the fish quite well. We’ve only replaced that unit once, mainly because the older pump seemed to vibrate and make a loud noise like its little internal bellows were running ragged.

The only other thing to do once a fortnight is to check the pH and adjust mainly with hydrated lime the tendency of the system to gradually edge to the more acidic side of things. Its pretty much a no-brainer once you get used to balancing out the system. Other than adequate access to reliable power to keep an aquaponics system running, you can grow out some very nice fish. We’d like to try trout next but given our warm temperatures, it would have to be a very short season to manage trout in a semi tropical environment.

So whats on the menu tonight?

Aquaponically grown Barramundi ready to be barbequed

Spicy Barbecued Barramundi

The New Zealand Government have got behind a $250,000 aid project and have built a trial aquaponics system on the Cook island of Rarotonga , located in the middle of the South Pacific Ocean.

Many of the Islanders have limited access to fresh water and lacked suitable soil for producing food.  Given that a lot of fresh vegetables are flown in from New Zealand making them very expensive, it seemed aquaponics was the better way to go.

The project is housed in a 200 square metre shed at the Titikaveka Growers Association premises, where tilapia fish will be fed high-protein nutrients.

The trial system has been a big hit with the locals who were surprised to see how quickly the vegetables grew on fish waste.

If successful the scheme may be rolled out throughout other pacific islands.

The New Zealand trade Commissioner Adam Dennniss is a big fan of the system.
“Show me a growing solution that improves yield without clearing more land, gives me a protein and vegetable crop, uses 90% less water is environmentally sustainable and economically viable whilst reducing the need for expensive fertilisers and I’m happy to look at it. Until then, I believe this may be a solution.” Adam Denniss, PT&I Trade Commissioner said.

Speaking to ABC Radio, Adam Denniss said “We built three different systems. They differ in size and scale. We have a two bed system. A four bed system and a twelve bed system.”

The 12 bed system is producing close to 350 to 450 head of lettuce per week.” he said.

The average wholesale price for lettuce in the Pacific is $3 per head so scaling up to a larger commercial aquaponics system is a feasible proposition given that the local labor costs were low.

Stress is a big killer of fish. This barramundi grown in aquaponics has a fine slime coating preventing bacterial infections.

Recently a friend was telling me about how difficult it was to grown strawberries in his aquaponics system. He didn’t have any success in growing them and was wondering if he was doing something wrong or indeed, if this aquaponics thing was over-hyped?

He didn’t have a green thumb he said, because certain other plants in his system weren’t doing too well either.

Closer investigation revealed that the fish were not happy and some had even died. Some of the surviving fish had bacterial infections on their sides and looked distressed.

An aquaponics forum had suggested that he add salt into the system to rejuvenate the fish. This worked to a certain extent but his fish were still progressively dieing and the salt level was affecting salt-sensitive plants like strawberries.

We noticed that the site where his aquaponics system was erected was placed in a poor location. Sited under balcony eaves, it hardly got any sunshine throughout the day so the plants looked weak and spindly. Not robust and healthy as they should.

No matter how good an aquaponics system is designed and built, it still must adhere to some basic principles of growing food.

Strawberries grow well in aquaponics but don’t like salt in the system.

It must be sited in a sunny location that has around 6 hours of sunshine per day. If you run an indoor system then you must use grow lights to enable the plants to grow. We regularly clip a tall hedge plant that threatens to block the sunshine from falling on one of our grow-beds. Keeping the sun shining on your growbeds makes a big difference.

Monitor your sunlight and watch where the shadows strike in the morning and afternoon. Are there any overhanging trees or branches that should be trimmed? If you are fortunate to have a nice sunny spot near your house then that is the ideal location to site your system.

It seems like common sense but there are a growing number of people who place too much reliance on the “miracle” of aquaponics to solve basic plant requirement issues and fail to understand the basics principals of normal gardening. Don’t let the technology fool you. People too often get swept away talking about pumps and plumbing and forget that the system is basically using nature to do all the heavy work.

So back to the friend with a poor system and why his strawberries and fish weren’t happy. He had setup a system in a bad location and then compounded his problems by stressing his fish! Everyone who came to his house was treated to a look at his struggling fish. Out they came in the net to be viewed.

Inevitably their natural slime coating was disturbed. Fish have a slippery slime coating that covers their scales and skin.

The slime coating acts as a defensive barrier to protect against nasty bacteria, fungal pathogens and parasites.

The constant stress of netting the fish aggravated the situation. Fins were caught in the netting and sometimes the slippery fish were dropped and injured as they flipped on the ground.

Stress is one of the biggest killers of fish. Don’t aggravate your fish with unnecessary handling. Adding salt as a tonic to the system up to 3ppt or three kilos of salt per 1000 litres of water can help the fish recover but it also compounds the situation with growing salt sensitive plants like strawberries.

The simple rule of thumb is site your system in a sunny location. Don’t stress the fish. Have an adequate number of fish to provide the nutrients to keep the plants well fed. Add a little maxicrop or seaweed concentrate extract to provide additional nutrients not found in normal fish feed pellets.

A heavily planted aquaponics system in full sunlight should have plants leaping out of the system.

Occasionally if you notice your plants looking a little yellow and not that rich vibrant green. Adding a little chelated iron will strengthen their colour and eliminate any plant weakness. Chelated iron is a soluble power that enables plants to take up the iron through their root system. Keeping your pH at around 6.8 will mean the plant can take up nutrients at an optimal rate and develop at their peak capacity. Throwing a rusty horse-shoe into the system doesn’t work as an iron substitute. We have tried it!

One or two teaspoons of chelated iron added every few months is more than enough to keep your plants healthy and happy. We rarely have issues with our fish and leave them alone to grow and develop normally and they reward us with providing lots of nutrients for the plants to take up. In fact the less interaction you have with the fish, the better.

By changing the location of his system and placing it in a sunny spot in the garden, our friend was able to eliminate potential problems from compounding. He also maximized both his fish health and plant growth.

Here’s a great idea for a Chicken coop built to fit the dimensions of straw bales. A simple four post construction with a raised floor and tin roof is all you need. Both sides of the chicken coop have a temporary straw-bale walls that keeps the coop warm in winter and cool in summer. Chickens lay their eggs and roost in the center of the coop. In the springtime you replace the straw with fresh material. You don’t need to build any extra timber walls as the straw bales will keep the elements from entering the coop and keep the chickens nice and cosy.

The discarded bales can be either used as mulch bedding for the garden or used as deep litter for the chickens to scratch through and fertilize the material. Either way, its an efficient way to build your coop and keep the chickens happy.

This version was built by Dr Kirsten Small a permaculture enthusiast who had this coop built on a slight slope in her backyard garden. Having the coop positioned up the slope allows any nutrient runoff in a storm to feed the bottom part of the garden. The tin roof also collected all the rainwater that fell into a 220 litre blue barrel. The water was then fed to these neat little chicken nipple drippers. The chickens when thirsty would nudge the nipples and a small amount of water would drip onto the plastic saucer arrangement. The chickens soon figure out how to get a drink and prevent fouling the water if it was kept in a conventional drinking bucket.

Chicken Tractors

Kirsten also has a large hoop “chicken tractor” that she places over her old garden beds to get the chickens to dig up the garden, fertilize it and eliminate any weeds, pests and seeds before replanting her garden bed. A few weeks is all it takes before the chicken tractor is nudged down the garden for all the chickens to resume digging and weeding her garden for her. Replanting all the old straw bale hay from the walls of the coop as mulch back onto her garden completes this neat little Permaculture idea.

DIY Strawbale chicken coops make great insulation and sound proofing capabilities if you have roosters in the suburbs. The chickens have a cosy home to roost in at nights. Having a high platform also prevents rats and mice from moving in as well. Extra space below the coop allows the chickens to have a cool spot to escape the sun or rain during the day. You also get the advantage of not needing to spend additional money on cladding your coop with side walls. Kirsten says her daughter likes the cosy feel of the coop so much she wishes she could sleep in it!

Radial Flow Settlers are a type of filter that removes all the gunk and fish poop that occurs in a recirculated aquaponics system. Handy if you have overstocked your fish tank or over-fed the fish as the water quality suddenly gets murky and is less than pristine.

How does it work?

Fish effluent enters the center of the tank vertically and flows down through the stilling well, causing low-density solids to be easily settled out of the water column as they settle at the bottom of the tank.

Filtered water overflows a weir at the top of the settler into a collection trough where the clean water is sent off to the grow beds.

Commercial Radial Flow Settlers are expensive to buy.

Build your own Filter Cheaply

Thankfully you can build your own for under $100 if you’re reasonably handy and have some time to spare. You’ll need to find a good clean 200 litre blue barrel. For an average sized home system, the 200l blue barrel filter should work reasonably well. Look for the barrels on online auction sites as they sell for around $30-$40 or you can ask around shipping and storage companies in your local town.

[swfobj src=”http://www.ecofilms.com.au/wp-content/uploads/2012/08/Radial-Flow-Filter.swf” width=”350″ height=”450″ align=”centre” allowfullscreen=”true”]Sorry you need a flash enabled viewer to see this cool animation[/swfobj]

The flash animation on this page shows the principles involved. The central stilling well should be large enough for your hand to reach down unimpeded for maintenance.

You will need to have the stilling well centered in the barrel (not shown in the animation) with some stainless steel supports or timber rods to keep it level and in place.

Fish solids as they enter the barrel will swirl and drop down and eventually sink to the bottom of the barrel. Cleaner water taken from the top of the barrel will flow onto your growbeds or floating raft systems.

How efficient is it?

Radial Flow Settlers are said to be highly efficient. They wont remove all the suspended particles from the system but do a fine job in removing up to 48% of suspended solids and are said to be more efficient than a conventional swirl filter. You can read a scientific study on their usage here: http://www.w-m-t.com/library/pdf/Radial_Flow_Settler_Whitepaper.pdf

Bucket and funnel added to the system to capture the solids

Optional Extras

You get get super fancy and add to this system. Replace the central stilling well  with a bucket.

Replace the bucket’s base with a large funnel to capture and direct all the settled fish waste. Attaching the funnel to the bucket might be a challenge and perhaps some plastic welding or silicone will be needed.

You could experiment with an outlet pipe attached to the funnel and a suitable tap fitting to direct all that fish waste out from the system.

But should it be all removed and eliminated?

Why not direct all that wonderful nutrient to another tank that is not connected to the aquaponics system? Why not a wicking bed system to grow all your root crops?

Now that would make a great inventive addition.

Here’s a great little DIY Radial Flow Settler explained in this YouTube video.

Notice the little weir around the perimeter to further eliminate solids.

From the land that can miniaturize everything, Japan is on its way to revolutionize the way people grow food in small apartments.

This miniaturized aquaponics system could double as a home aquarium system that also grows a few lettuce heads in its circular floating raft system. All powered by decorative tropical fish.   Its also designed to act as a therapeutic display that is also both functional and attractive.

This system  consists of a fish tank and a vegetable planter, which are connected by pipes. It utilizes the fish waste as nutrients for the plants, in a symbiotic closed-loop cultivation system.

This compact design, where the water, ornamental fish, and vegetables can all be seen together, was created by AAC an aquarium production company.

A spokesman for the company said “In this system, the fish droppings are decomposed by bacteria, so they become organic fertilizer for the plants. Aquaponics isn’t yet widely known in Japan. So we’ve designed this product to introduce aquaponics in the form of a display. We hope that, if people understand the concept, aquaponics will become widespread.”

Because the effluent from the aquarium is consumed by the plants, the tank water doesn’t need changing so often, and the cultivated vegetables can be eaten. So, this system offers benefits apart from being a display.

“As an interior display, we think this system’s initial benefit is therapeutic. So we’ve created a soothing image by using curves, and we’ve eliminated the corners for safety. This display is also well-lit, so the plants grow well, and the fish look pretty.”

“Currently, we’re using lettuce, but flowers can also be grown. We expect this system will be used in cafes that feature organic vegetables or relaxing themes, and in nursing homes, hospitals, and the like. If people who can’t get outside easily can plant vegetables indoors, we think it could be therapeutic.”

This version will be priced at 300,000 yen (~US$3,800). N.I. Teijin also plans to offer custom-made versions.

Ouch! $3,800 is a bit pricey but it should give you some inspiration for making your own indoor system. All you need to find is the right perspex tubing and grow-lights and some imagination in the workshop.

Photos from Aquaponics enthusiasts around the world, showing off their CHOP2 system all based on Murray Hallams innovative design.

IBC or Tote tanks are an economical way to get started

A year after Murray Hallam revealed the plans to build your own aquaponics system in his popular DIY Aquaponics DVD, the photos from aquaponics enthusiasts are now flooding in.

Built from easy to get tote tanks (IBC or International Bulk Containers) people all around the world have taken out the angle grinder and chalking gun and built their inexpensive systems based along Murray’s CHOP2 method. This easy to build method allows people to build their systems on irregular ground and control the flow of fish nutrients to any bed or fish tank for easy maintenance.

A look Murray’s popular forum reveals heaps of proud owners sharing photos of their new systems based on CHOP2.

The distinctive three grow bed system with sump and fish tank are springing up in backyards around the world. This simpler approach gives confidence to backyard tinkerers the ability to grow fish and plants together very productively.

Aquaponics has certainly taken off judging by the number of photos.

Murray Hallam’s DIY Aquaponics DVD that teaches people how to build a CHOP2 system with pdf plans included.

Although most people have built their systems up off the ground on concrete blocks, its interesting to see a number of user innovations and aesthetic changes to Murray’s design. Some very sturdy timber framing and screening work allows the design to meet the needs of people wanting a more attractive look and to hide some of the rough edges to the tanks.

The additional features of strawberry towers and NFT channels to grow lettuce shows people experimenting off the standard plan and adding their own touches.

Its a great way to get started in Aquaponics.
