Just wondering if this powerhead is too much for a 3 gal pico. I have the 240gph but have not put it in the tank yet. I have a Aquaclear 20 HOB at highest flow rate, is this enough water movement? I plan on adding a clownfish in the tank but I want to add some corals as well. So far there is nothing in the tank but live rock, sand, the aquaclear and water.
