I have a situation I've never had before, it is almost funny. I set up my tank that came with a 40 gal sump that also included a protein skimmer in the sump. Wait till you see the pics! Anyway I could tell the fit was tight, but little did I know that once everything got running, I would have a problem. I went to empty the collection cup from atop the skimmer and it will not clear the top of the sump to be removed. I then remembered that when I installed the collection cup that we did tilt the sump to put it in, but now with water in it there is no tilting the sump. So my thought now is to drill a drain hole in the side of the cup and attach a hose that will go to an alternative collection cup so that it can be emptied. Any ideas on this?
