I have had my 250 up and running for 3 weeks this coming Sunday, and it still seems to be not pulling really anything much, I have the air full open, the pipe restrictor for the return is 3/4 towards the close, the bubbles are popping aroung the bottom of the neck, for a short period you might get some form action but not very long.
Just wondering if there is something wrong, because all I have read is incredible stuff about this skimmer in pulling a lot of crap out of the water.
Any advise would be appreciated
