Prevent an Aquaponic Disaster

When someone new is getting into aquaponics, they need to take the time to carefully review and learn about aquaponic system maintenance. They need to learn about the most common issues that cause problems in aquaponic systems and it will help them to be more successful from the start.

One of the most disastrous aquaponic problems that can happen is when you use cold, chlorinated, un-adjusted pH water to top off and fill the system’s reservoir. Using this type of water will stress and kill everything from your fish and plants to even the healthy bacteria living in the system.

When you are “topping-off” the reservoir in the aquaponic system, you can get away with using less than 10% of this type of water. However, using too much will cause aquaponic problems in a very short time and you will need to start salvaging your system all over again.

Many times, people who are topping of their system using a water hose will forget that the water is on and flood their system. By setting a timer it will remind you to shut off the water to avoid this aquaponic problem.

The Options

Always evaluate the situation first.

Figure out what is wrong, ways to fix it and then pick the best option. Using chlorinated water essentially sanitizes your entire aquaponic system and will possibly eliminate all of the gathered plant nutrients.

When using cold, chlorinated, un-adjusted pH water for your system, the most likely state of each of the living elements in your system are as follows:

The Fish

Chlorine is not good for fish and the best case scenario is that they are just really stressed. The temperature level of their water most likely decreased considerably and the pH of the water is most likely changed.

While it is best to not utilize aquarium dechlorinators since they add sodium and other chemicals that can be hazardous to plants and cause aquaponic problems.

You should reduce the amount of chlorine in the system as quickly as possible to recover the fish’s slime coat that keeps them healthy, using a good aquarium water conditioner will do both of these things.

In extreme aquaponic problem cases, many of the fish may be very sickly, or floating in the water.

The Plants

Your plants also are stressed as a result of the temperature and pH changes, in addition to the chlorine that is presenting the water.

If your aquaponic problems are extremely bad then you might have to clean the system, which removes all of the beneficial nutrients from the system. It is strongly recommend that you add some Maxicrop into your system that will feed your plants while the aquaponic system comes back into balance.

If you catch the aquaponic problem before the water has made its way from the fish reservoir into the plants in the system, then quickly shut off the water pump. You will need to treat the fish tank water before you turn the water pump back on and by doing this it will help to minimize aquaponic problems caused to your plants and the bacteria in your system.

The Bacteria

Likely, the healthy bacteria in the aquaponics system have been destroyed and you will need to start all over again by re-cycling your system.

This is the hardest part since you most likely still have fish in your system and if they all didn’t die, you will need to cycle your system using the fish as your ammonia source.

Unless you have another fish tank or aquaponic system that you can transfer them to and do a fish-less cycling.

All will work out, however be sure to watch the ammonia and nitrite levels very carefully. If either starts reaching the high end of the color graph in the API test kit (4 ppm ammonia and 1 ppm nitrites).

After that be sure to do a 1/3 water change out of your system to dilute the levels back down to where your fish will be able to tolerate to avoid further aquaponic problems.

The Worms

You can assume that they have actually been eliminated by the chlorine and that you should add more worms to your grow beds once you have adjusted the water.

The bottom line is that one disruptive aquaponic problem can reset your system back to when you first started. You may lose a few fish, your plants could stress out and yellow for a few days or weeks, but you will certainly recuperate from the aquaponic problems.

Learn From Another’s Experiences…

The best way to prevent these aquaponic problems is to use a separate water tank to off-gas the chlorine, adjust the pH and water temperature before transferring the water into your aquaponic system.

By doing this additional step, you will save time and heartache from an aquaponic problems turning into a disaster then having to start all over again.

And just think, you will most likely never make these mistakes again or by reviewing this article, you will prevent this aquaponic problem from ever happening!

  

Permaculture + Aquaponics = Self Sustaining

By bringing Permaculture Design principles and practices into Aquaponics, we are closing many loops, inefficiencies, and energy drains that exist in more conventional systems, as well as integrating the system appropriately into the larger landscapes and ecologies it is a part of, making it a much more holistic and sustainable enterprise. 

Closed-Loop Aquaponics focuses on designing aquaponics systems that that produce as much of the system’s needs (water, energy, fish, feed, heat, gas, etc.) on-site and within the system itself as possible. 

Products of the systems can include; solar electricity, solar heated air, solar heated water, fish, prawns, vegetables, fruit, aquatic plants, algae, minnows, snails, worms, dry and liquid fertilizers, methane gas, and more. By using the Permaculture Design process, we learn to design systems appropriate to diverse climates and unique ecological niches to meet various needs, dreams, and desires.

Aquaponics and Worms

Vermiaquaponics is actually a word my father and I invented. It is in laymans terms the same thing as aquaponics but with a combination of worm breeding. You use the worm castings to make a nutrient tea which is then used to feed the plants through their roots directly and in the form of foliar feeding. Foliar feeding is when you feed a plant through its leaves. You spray the tea onto the leaves directly and the goal is to have the nutrients be absorbed in more than one way. Then the worms themselves are used to feed the fish thus eliminating some of the cost of fish feed, and making these aquaponic systems more self sustainable.

Vermiaquaponics will soon become the future of aquaponics. In a way many people use certain aspects of it by feeding their plants with extra micronutrients and such.(for example chelated iron, manganese, zinc, etc) But what makes this version so unique is that it will help eliminate the cost of fish feed which becomes an enormous expense. In addition you are feeding your fish great protein which should theoretically help them to grow faster and bigger. Although worms do not give fish 100% of their diet, and are nearly 90% composed of water, so supplements will be required. So essentially your getting your fish wish less cost improving your profit. 


One concern I have about this new form of growing is when it gets to the commercial scale. Places like the University of the Virgin Islands are harvesting over 5 tons of fish annually and in order for something like this to be beneficial to them you would need a very vast number of worms. Making vermiaquaponics less practical on a commercial scale but definately beneficial on the hobby scale. Something to consider if trying to convert from aquaponics to vermiaquaponics is that you will need the space to grow your worms, and to make sure you will have enough worms to be able to integrate this technology into aquaponics.

The focus on vermiaquaponics is to not incorporate it in systems producing such high quantities of fish. For the Urban Farmer, primary focus should be on plant growth in order to make profit. Using as little fish as possible and supplementing with tea will reduce other costs. The key is to get the right number of fish to plant growth ratio and also adding the vermiaquaponics side of the equation. When all these numbers can be worked out maximum plant growth to cost can be achieved giving you maximum profit.
