I was thinking getting a powerhead to help add a little circulation so I don't have a dead zone, but I have no previous experience with them, so I have no idea how strong/big of one I should get, or if I should even get one at all.
I'm not wanting to toss my fish around, just create a gentle push in the water to get it back around to the pump. I was originally thinking a small powerhead around 80gph or so, but I wasn't sure if that was too much or not enough.
powerheads take alot of room inside the aquarium why dont you get another filter and put it on the other side? a small one will do just fine top fin ones are good.
