I do something similar as well. I replenish my deep water raft system from the fish tank water which comes from the grow bed that has worms in the grow bed rocks. Then I top off my tank with rain water. The raft plants are growing great although I do provide constant aeration and I have a very small solar pump that circulates the water a couple hours a day if the sun is strong enough.Originally Posted by mommyhen42
