I have a red sea prizm deluxe skimmer. I have had it set up for about 8 weeks. I set up my new reef about three and a half months ago. I lost the book and am not sure if I have the thing set up properly. I have never gotten any fluid in the collection cup, but there are some bubbles which have risen up through the chamber. Is this normal? I do have 4 fish, a clean up crew, and some ricordias. The only time I saw it really working was when I forgot to unhook it after adding melafix.
I am not sure how much gunk I should be getting at this point. If anyone has one of these, some tips would be appreciated. I know they are touchy.
