Okay so if anybody is in the market to get a nano skimmer take this write up into consideration. I couldn't find a skimmer to fit in the small space. There's only one skimmer out there that would work for me. There was still a possibility that it wouldn't have fit plus I would have been spending over $100
So the items you'll need is some kind of bottle or tube that will fit your space I found drink bottles to work the best for This because you can utilize the the water tight seal in the cap of most drinks
