I just bought a 56 gallon tank and I am wondering if I really need a protein skimmer. Why is my skimmerless freshwater tank super healthy without a skimmer? I know that skimmers don't work for freshwater, so why do I need need one for my new cuttlefish tank? If a skimmer is a must, do I need one of those $200+ ones like aqua c remora or can i go with the "up to 75 gallon" $30 skimmers by Lee's pet products at my LFS?
