I have a 90 gallon tank, saltwater fish with Live Rock in it. I have 2 Ehiem 2217, and a 3x 9w turbo twist UV light, but I want to add a protein skimmer. My problem is that my tank is only an inch and a half from the wall, because I needed to rest the tank's weight on the main beam which runs across the room. It is enough room to run the tubes down the back of the tank. Now that I am looking into skimmers online, I am only seeing products that hang on the back of the tank. I have a canopy on the top of the tank which also makes it difficult to hang it off the side as well.
Any advice is welcomed.
Thank You
