so you have them on a wave maker and it actually makes waves like that? i thought when it said wave maker it just made the power heads pulse on and off. not actually make a wave at the top of the tank!!! i have never seen a tank actually have a wave like that. that is really cool i like how the corals swayed back and forth like real life. but that is a lot of flow!! what is that like 30,000 + gph?
