Hey everyone, I just recently got a 210 gallon used tank for a great deal, and wanna make it a saltwater. But I’m worried it’ll cost way too much to maintain per month. About much would I be spending on salt a month? Would it be cheaper to under stock the tank a bit to let me do less water changes and save salt? I’m a noobie when it comes to saltwater. I do not plan on making it a reef tank. Any help is appreciated!
