I just picked up a remora pro for our reefer site in Vegas. I hooked it up and it's collection cup seems to fill within an hour and I have the cup all of the way up. Also a lot of the micro bubbles seem to push out the side of the collection cup before it even makes it to the neck. Does anyone have any experience with there because I am lost at what to do to fix this problem. And the skimmer has not been in use for like 2 years or so the lady I bought it said.
