I first got really excited about the idea of fish tank aquaponics after following the above project on Kickstarter a couple of years ago. The project described the idea as “a self-cleaning fish tank that grows food” and that’s exactly what home aquaponics or fish tank aquaponics is all about!

I think it’s safe to say that fish tank aquaponics is somewhat trending. The Kickstarter project was a huge success – getting 249% funded by the end. Setting up your own home aquaponics garden is also something that is really easy to do and can be quite rewarding.

Fortunately, fish tank aquaponics doesn’t require a degree in quantum physics to understand. Fish produce ammonia-rich waste and nitrates as they go about their daily business; this waste-water is pumped into a planted growing bed, which fertilizers / feeds the plants; and the resulting water (which is now pure and waste-free) is filtered back into the fish tank. The beauty of fish tank aquaponics is that it is a closed system, which means that if one gets it 100% right, you will never need to clean your fish tank or water your plants!

I’m taking a bash at setting up my own home aquaponics using a 100 litre fish tank, a herb box and some ferns. The idea is that the ferns will eventually grow around the fish tank – creating something rather aesthetically pleasing. But have a look at what some others have come up with. I’m particularly inspired by the multi-layered fish tank aquaponics setup. It’s a good example of indoor vertical farming or windowfarming.

It’s important to note that one does not use soil with fish tank aquaponics, but rather small stones of between 5-10mm in diameter. The plants instinctively wrap their roots around the stones and don’t require soil at all. Also, if you’re not making use of a flood tank, it is important to consider choosing plants that enjoy being constantly hydrated, which is why I decided to go with moisture-loving ferns.
