I was hoping someone might be able to help me. I setup a 110 with a built in to the tank wet/dry filter, similar the seaclear system 2. It has an overflow that flows over floss, then bio balls and a pump shoots the water out the bottom. My question is where should my water level be? I have it filled nearly to the top over the overflow, however, I'm thinking this is incorrect. The bioballs are covered with water, hence it not being wet/dry but just wet. Should the water level be at the point where it's just pouring over the overflow? Any help would be great and thanks in advance.....
