just asking . some times people give advice and i go over board with it . I open the flow from my pump and put in two power heads. wooh yeah .blow baby blow
yeah other then the fish it is when the flow is powerful that water spills out of your tank. or if the flow or current is so strong that it blows corals off of there repective postions or it breaks corals.
could u imagine u start the pumps and just see the fish go from one side of the tank to the other and then get stuck to the glass unable to move. i think that would be funny. LMAO
but anyways i think of it this way if u could feel a good current with your hand going different ways u should be ok.
