I have purchased a maxi-jet 900 powerhead for my 60 gallon Jack Dempsey tank. I bought it to help witj dead spots, and dirty substrate. I was hoping someone could tell me the best placement. The back of my tank seems to be where debris is ending up. I have a penguin 350 and aqua clear 70 and bubble stone, so o2 is not issue. Any suggestions?
