Ok I am by no means an expert as I have only had my skimmer running for a couple of days. But my skimmer is very simular to yours and this is what has happened to me. Mine filled up like that the first few times i ran it. Thought i was doing something wrong also. I even left a post on here just as you did!!! I have the right pump for a skimmer and everything. My return line is opened all the way. I did put the little black hose on that came with the pump for more air. And it seems the thing has calmed down and started acting right. It now gets a little foam and fills very slowly, in fact last night was the first time I felt comfy letting it run with out supervision. It was only 1/4 full with water and that water was a nasty green and slimy so I figure it is working right. I know that this probaly don't help much but, maybe just give it a little time. I also figured that since I am just now cycling my tank that it just had allot of stuff to deal with. Hook up the extra air line to your pump, make sure your return is all the way open and just keep working with it and watching it. I think it will kind of settle out like mine did. But do keep me posted!!!! Good luck!!!!!  |
