Im in the process of tiling my 180 gallon (love it so far). I was looking for a decent powerhead to place at the bottom of the tank to keep debris from settling so the filters can catch it. But i have a idea/question i have 2 fx5s on the 180 how can i extend the output hose where its an inch off the bottom of the tank? Pvc pipes or a hose and would the output from both fx5 be stong enough to keep the debris flowing any input or ideas would be greatly appreciated
