interesting. that's very good at showing just how easy it can be done. hope my first effort looks that good, and of course hope my second effort blows it out of the water haha.

i'm going to use some gravel beds like they have in that photo, but i'm doing two rafts as well. basically the fish water will get any solids cleaned out in quite a few of those gravel beds and then gravity flow into the rafts, where salads and leafy greens will be floating, then the water goes to the sump and back into the fish to start all over.
