Sacred Groves was introduced with an Aquaponics system by a volunteer from Belgium, named Giri, back in October 2015. After which many of the volunteers and interns at Sacred Groves were inspired to have an experiment with a fully functioning aquaponics system. With Giri’s help the aquaponics system was completed with a huge bio-pool of size 11M X 4.5M in the center, a horizontal plant bed, three cylindrical filters, and a bio-filter. Almost 300-400 (tilapias) fishes were bought and added to the bio-pool within the following months and the aquaculture started functioning smoothly.
The horizontal plant bed consists of five 7M long PVC pipes, which are attached to the wall. Each of these pipes has small plant pots inserted in them at definite spacing.
The cylindrical filters mainly consists of three filters- a small filter containing pebbles, second filter with coir, and the third filter with sand. Thus when the water is pumped from the bio-pool to the horizontal plant bed through the swirl filter, the debris of larger size will be removed by pebbles, letting the water flow into the coir filter, where the particles of moderate size are removed, and then the water flows into the sand filter, which will take out the smaller debris and clear the water. This water is then constantly supplied to the plants in the horizontal plant bed, after which it flows back into the bio-pool, and this cycle continues. Thus with the completion of swirl filter, bio filter and the plant bed, the aquaponics system was all set to function full-fledged.
