I recently decided to start up a salt water aquarium again, and i was wondering if i should gt a protein skimmer. It's not a reef tank, but i have heard that a skimmer has positive effects in any salt water tank. So far, i have 1 Royal Gramma, 1 Chocolate chip star fish, and a horseshoe crab. Thanks, i was just curious because i have been hearing that skimmers are good, and i just wanted to know if i should get one for tank. And if you do think my tank would need them, do you know of any good skimmers on the cheaper side? Thanks for your time.
