Hello all I purchased a 35 gallon tank with a Penguin Biowheel 330 filter (relatively the same as the penguin 350) and just finished filling it up with purified filtered water. I'm really excited to get this tank up, my first tank! My problem is that my filter turns on, impeller spins but the water does not go through the filter. My buddy had this working last week. How do I get the water to start going through the filter for the first time? I know it sounds dumb but I never used a biowheel filter before. The impeller is spinning and the filter is clean with new biowheels, the other end of the filter dips in about 3 inches into the water. Any help would be greatly appreciated, and sorry for my ignorance thanks.
