Filter is made of plastic collander, window screen, polyester fiber fill. Has a styrofoam collar for flotation. Solids are lifted through 3/4" PVC with a 3/4" to 1/2" Tee at bottom to allow airstone insertion from the side. As air rises in tube it creates bubbles that make water in tube more buoyant and rises sucking in water from below together with the solid wastes. Notice the green vegetation residue on the screening material.
Controlled environment test: 175watt water-cooled HIDs on light mover over 22"x22" grow trays (aerated deep water raft system).
Hydro-organic production from mature bio-filtered compost derived from: rabbit manure, vegetable roots, kelp, rock powders, egg shells and bacterial & fungal inoculants.
We are in full swing with our Aquapontics this spring. Adult fish are still alive from the winter months and a couple of bumps in the road. We have new fingerlings in the tank as well and we have more on the way. Plants are doing better than I thought we are ahead of everyone. Tomatoes are tall and green beans are spreading everywhere. We are putting in new string everyday..New pictures downloaded.
