Hey guys I just setup a Petco Brooklyn 55 gallon metal stand for my 40 gallon long and the way it sits in my apartment the front water in the tank is higher than the back? I made sure the measurements from the floor to my tank were 30 1/4" all around. It has adjustable feet. But I'm not sure what I should do to adjust it? Suggestions please! Also my sponge filter keeps floating to the top of tank any idea why?
