I have a 55 Gallon tank with a canister filter and a protien skimmer. I also have a small power head that does not move much water. Can anyone tell me how many I should have and where to place them?
I have a 55 too. I have one on each end at the top, with hydro flos on them, and one on the end in the back pointing behind the live rock so nothing get stuck back there.
