My skimmer seems to not be working properly, it's a Southbay in sump skimmer. For some reason it is overflowing out of the top from under the lid and out of the holes in the lid. The pump is working fine and the airline isn't clogged, I don't know what else to do! When I cleaned it the other day, it was working, it had a lot of green nasty stuff in it and since I have cleaned it the top storage is clean and the bubbles are spilling out. I took a Nitrate reading and it was high ( I think the skimmer not filtering has something to do with it?) I'm starting to become concerned for all my fish and other things. If I loosen the ring so the top portion isn't secured it stops overflowing and seems to work better...I just don't understand! Please help this newbie!
