Where does the body of your skimmer is setup? My skimmer use to run great during breaking period, now during the day the water just boils and won’t raise at all, but comes night and it works halfway decent. It makes no sense, and this just happened after cleaning the cup after breaking period, so no sense to me, I contacted coralvue and they can’t do anything even when I tell them the pump must be bad, their answer is send skimmer and we will check it, but we don’t have replacement pumps to sell either.

like what the heck
