I have been going through posts for what seems like forever and I still can't make a decision. I need a new filter for my 10g. It currently has a whisper 10 HOB filter and there is not nearly enough flow in the tank IMO. I've thought of just getting a powerhead but I don't want to take up any more room in the tank. All the other HOB filters I've seen for bigger tanks have a split output and they seem too large to fit. Any opinions are appreciated. Thanks.
