I have a hexagonal aquarium and the glass lid covers most of the tank. I want to add a protein skimmer but there is no room to hang a traditional one. There is just enough space on one side for my penguin biowheel, barely. Does anyone know of any protein skimmer designs where I would just need a tube to go into the water and then the protein skimmer could sit on the table next to the tank, or under the tank?
