I got my live rock in my tank now, but was wondering if my powerheads were close enough to the top of the tank to get oxygen in it. How far from the surface should my powerheads be to oxygenize the water? Does the water get oxygen when it circulates to the top of the tank? So if I have 4 powerheads and the 404 working like one- carrying the water from one side of the tank to the other- I should be good on oxygen?
