To borrow an in sump skimmer? I have a rubbermaid tote that has 2 large GBTA and a 3" clone I put my Elos in my 90 so I could get the cycle up and running. I have some little pile of crap that came with the 72 gallon system I was given. I can't get it to work properly and am fed up with trying to do so. Or, if you have a really cheap one, I may end up buying one for a spare. I will be more than willing to pick it up or pay for shipping to get it to me. Any help would be GREATLY appreciated.
