Thanks lesa

, I have been playing with it sense this post and I really don't think the setup is a problem. I shutdown the fuge for 1/2 a day, moved the fuge supply behind the skimmer for a few hours and there was no more production... I just think for some reason there is not as much to skim...

I have stopped using Liquid Vert and went to DTs... That may be some of it?
