The problem actually went away after I left the skimmer unplugged for a couple days, not really sure how that happened...
I have another question though, the magnet that comes with the reefpack 200 doesn't really line up with the holes on the filter and skimmer so they have to be kind of at an angle to be attached to the magnet, would it be possible to retrofit the individual magnets that come on the regular tunze 9002s?
Also I've had the skimmer running for a few weeks now and it either produces nothing or overflows randomly, is this normal for a break in period?
