Early experiments - 70 liter Aquaponics using aquarium

When the NFT system started to grow, i began looking up online about aquaponics and came across a lot of content and realised this is a wonderful food production system.

So i decided to try a small growbed system. I had few small tubs and an old decommissioned aquarium lying around and so i decided to make use of it. So first i built a wooden table, just to hold the growbeds/tubs above the aquarium.

After a visit to the hardware store, I created the siphon mechanism using pvc pipes and connected the water flow mechanism whole system. I did not use any taps to regulate the water flow as this was an early experiment. Just wanted to see how basic can this setup be.

My NFT system was giving a bit of a problem and so i decided to transplant all the plants form there to this grow bed system. Since i wanted to remove the NFT system and plan a bigger Aquaponics unit in its place. The transplanted tomatoes started to grow really well. This system has a 70 liters aquarium below the tubs and it has 10 goldfish and a few guppies.

Days, weeks and months later ... lust look at the way the plants have grown and in 4 months time of just feeding the fish twice daily and topping up water as and when the level dropped a little due to evaporation. After this system completed six months i learned a lot about the simple science behind aquaponics, and once you follow those life becomes easy.

I learnt a lot like the right size of growbed, the right growing media and size the water flow rate how it drains out etc. Then i decided to go bigger .. My next project a 500 liter aquaponics setup.
