Hello, I got a few questions. See Iam setting up a brackish water aquarium for my baby diamond back terrapin I acquired yesterday. Iam setting him up in a 55g for now, and Iam using sand. I was wondering, what is the best protein skimmer for the best price? I dont want to go over 100-200bucks(220bucks is the most id like to spend) Also I wanna use live rock, but my father worries that itll break the tank. How many pounds of live rock can a tank hold? Also Iam using a mix of rock salt and cichlid salt. How many cups of rock salt should I use to make atleast 1.009 in a 55g(Say exact water would be, 40-50gallons or so). also what else helps keep the tank clean and parasite free? I do water changes weekly. Right now Iam just trying to cycle the water. What are some strong hardy fish that can go in a 55 brackish tank?
