Aquaponics Fish Tank Cover

A 275 gallon IBC tote repurposed as an outdoor fish tank for my aquaponics system.

The cover serves a few functions.
1. Reduces light to help curb algae growth
2. Keeps leaves and other debris out of tank
3. Most important: Keeps kids out to the tank! Murray Hallam of Practical Aquaponics says, in his Australian accent, “Kids and water is a dangerous mix. Kids, water and fish is diabolical.” (I just thought that was really funny.)

The cover is made from the same solid, (not laminate), hickory hardwood flooring that I used to build this project…oops I was going to reference another project but I apparently neglected to post it on LJ. I’ll add the photo here from my webpage. I will post that project here on LJ when I can access the pictures on my currently broken computer.

The “pickets” of the Tank Cover are all solid hickory. Anyone who has ever worked with hickory knows how hard and heavy it is! I didn’t have any pieces long enough for the “rails” so I used some red oak I had in the shop.

The finish: Two coats of boiled linseed oil for protection and to darken the wood a little. Followed by two coats of spar urethane for ultimate rain and UV protection.

Thanks for looking!

Very good, Dave!

I’m going to have take a closer look at those IBC totes… to really see what they’re all about…

So, you going to have fish swimming around in this tank pumping (recycling) the water through your complete aqua garden system?

Fish living in the dark?

What kind of fish you going to use? Gold fish?

I guess there is a certain amount of fertilizer in the water being circulated? Is that the objective?

Will there ever be a Temperature problem?

Thank you.

Thanks guys!

Joe,

The fish will be Tilapia. Right now I have some comets (goldfish) to cycle the system. The idea is, the fish produce ammonia through their respiration and waste. The water from the fish tank gravity feeds into the grow beds that are filled with a media. In my case, I used white river rock.

Bacteria establishes a home in the media. One type of bacteria converts the ammonia, which is poisonous to fish, into nitrites. Another bacteria type, converts the nitrites into nitrates. Nitrates are plant food!

Aquaponics combines hydroponics with aquaculture. You raise fish, which you can consume if so desired, and vegetables organically without the need of the nutrient solutions required in hydroponics. You are creating a mini ecosystem.

The grow beds filter and clean the water for the fish and the plants consume the nutrients produced by the nitrification process. (The nitrogen cycle.)

Temperature is not a problem for me as I live in sunny South West Florida. Tilapia are a tropical fish with a wide range of temperature tolerance.

As far as the dark…it’s not completely dark in the tank. Some light gets in through the slots in the cover. Fish actually like dimly lit environments so it is beneficial to them as well.

It’s all really cool and fun. Plant growth is amazing.

Thanks Roger. I didn’t really think of it until it was done but if I were to do it over again, I would have round the front corners.

Dude…that rocks. Aquaponics may be the wave.

Have your say...
