I set mine up to stream under the lid instead of drip in to the pots. But one thing else I did was instead of capping off the 1/2" hose, I put a valve at the end, so I can leave it open slightly. It stirs the res water constantly that way, and if I want more or less drip/stream, I just turn the knob a bit. Moving water is more dissolved oxygen too, so I think it's a nice way to go.
