So I am new to the saltwater tank Hobbie and I'm starting a 40g saltwater FOWLR tank. I have 40 lbs of dry rock from BRS curing in a brute trash can with saltwater, powerhead, heater, and started it with bacteria. I tested the water after a week and still have ammonia showing at 8ppm. Is there something else I should do or is it just a waiting game? I'm new to this so any help is appreciated.
