Anyone else turn powerheads off at night?

so, are the skimmers what produce most of the oxygen in the tank? i guess i was thinking that when the water crashes down in the sump, and goes through the skimmer, a the amount of oxygen mixed was sufficient..... is this true? If it is, then in that case, would it be more correct to say that you shouldnt turn of your return pumps at night?

That sound sabout right to me. I only turn off my C/L which dosen't enteract with the surface anyways so thete is no way to add and gas exchange. My skimmer and sump return run 24/7 other than cleaning. I have a hammerhead for a return pump, 5000 GPH so I'm not worried about losing the gas exchange by shuting down my other pump.

However, a lot of people do not run as much water thru their sump as I do so they may be concerend about shuting dwon a PH that may be agaitang the surface water.

On my smaller tank, 45G I do not shut down the PH's as I don't have room for another timmer on that system. Plus there is not as much of a Poop load or high flow on that tank. It's a LPS, shroom, zoa tank.

what dimensions are your 45? i have one, that is about 24x24x18, and i was looking to maybe to get it replaced because it is old, has scratches, needs to be replaced... so if your tank is the same dimensions, where did you get it and who makes it?

My 45 is a hex tank that I've had for about 10 years. It's been a reef for about 7 of those years. It's glass but does have a few scratches in it. Some pic's of it are in my gallery.
