The powerhead stopped working. I shook some hair algae loose and it got caught in the impeller. I suspect that's why it stopped working. I considered just going without it but I noticed the fishies hanging out near the top which seems to indicate low oxygen. Having the powerhead aimed upwards really seems to oxygenate the water...so really it's an oxygenation thing. Otherwise I'm not convinced that flow serves any real purpose.
