I'm new at salt water tanks and need some advice about skimmers. I set up a 65g tank with a 20g sump. I currently do not have a skimmer. The price of skimmers is far too high to purchase one so I'm looking at building my own. The plans I've seen have 4' to 6' skimmers. Huge! I'd like to put an in sump skimmer and need plans for it to fit under my tank stand. Is it OK to modify these plans to adjust the height? Is it really necessary to have 4' tall skimmer? Anybody?
