I have an eclipse hood that flows at 250
GPH, and an Aquaclear powerhead that flows at 175
GPH. Actually I have two powerheads, diometrically opposed, alternating on/off times every twelve hours. Should I have them both on at once? If so, should I move them so they aren't facing eachother? I heard something about mimicking the ocean tide, was just testing it out, is this a good way to do it? I know 12 hours isn't exactly the right time cycle, but you get the idea...
