Hi everyone, I'm a new member and really enjoy the forum, I really learnt a lot from all of you, thanks! I'm trying to cycla my tank after some ammonia spike want out of control. I have 6 zebras and one rubbernose, the tank is not planted. I used Tss a few days ago and my ammonia is really going up, more than 2 ppm. Is it safe for my fish? Can i use prime at this point? Thanks!
