:? I have a new 90 gall All-Glass with built in overflow and their model 3 sump. Im using a Ehim 1262 pump. Why does my water in the overflow constantly change height about a inch. Its girglying and making very loud noise. It seems like the drain doesn't keep up with the return or the drain...
So did you stick the hose down the overflow box or the drain tube. My drain tube has a hole on the top for air. That is what seems to be the problem it seems like the hole needs to be larger.
