so i upgraded from a nano 70l tank to a 400 litre tank and sump i bought it from another reefer and it had been running for about 4 years, I decided that while moving the tank i would upgrade a few of the bits and pieces to make it better for the future so i decided to get the bm curve 7 protein skimmer.
i set it up in the sump in the second chamber and it wasn't working very well so i raised it up an inch and BINGO it started working straight away and pulling a good skim!! i was really pleased with it. so about two weeks past and i cleaned out the cup, i gave it a really good clean so it was all tidy but now i can't get it too work anywhere near how it was

I've tried moving it to another chamber I've raised it another inch so its in about 8 inches of water, I've tried lowering it again i have tried everything and i just can't seem to pull a dry skim anymore and its driving me mad it just allways overflows and fills with water on every setting
Can any one help me please
lol
