Do you see the water level when you look at your tank fron the front? When I setup the tank for the first time, I was greatly concerned about not providing enough O2, so I didn't fill up the tank completely to the top, and let AquaClear create surface disturbance. I have to admit, I was also afraid of tank giving up, so I didn't want to add more water... :D Over the past couple of months, I "accidentally" raised the level after each water change. Now I can barely see the water surface from the front, and I don't see any fishes needing additional O2, so I'm guessing that was not needed from the begining. It is certainly MUCH quieter than before...

So what water level do you keep your tanks?
 
I keep mine as about a half inch below the lip of the tank, so you can't see the water line.
 
Most 'standard' size tanks have more than enough surface area to provide plenty of oxygen exchange. Even a gentle ripple across the surface can almost double the available surface area for gas-exchange. Lack of oxygen is not likely to happen unless your tank is enormously overstocked(ie: feeder-fish tanks), or is extremely polluted. Very tall, narrow tanks and fish bowls can have problems, as well.
 
Re: Water Height

I keep my water line about 1/4" (corydoras julii tank) to 1/2" (betta tank) from the bottom of the black plastic skirt on the top of the tank. This works for me. I don't want the water any higher in case I have to stick my hands and arms in to add or remove a plant.
 
Over the frame, I dont like to see the water line.
