I was gifted a coral as a present but my main tank isn’t cycled. I put the coral in a smaller tank with clean salt water, but I tested the ammonia recently and its around 1ppm and im really worried I am going to kill my buddy. I’ve already done a 50% water change and cleaned the filter. I got the filter used and I believe thats where the ammonia is coming from so I guess I just didn’t clean it well enough before. Anything else i can do to keep it healthy?
