Goodmorning Carlos,
I appreciate your quick response. I have 2 Bartlett's anthias, 2 clowns, yellow headed sleeper and a yellow eye Kole tang. I took the pump apart 2 weeks ago, and I didn't notice the impeller or impeller shaft being broke or damaged. I'm guessing that I have a skimmer that is to big for my tank due to the range of the skimmer and in return is the reason for the skimmer not skimming?
