I am glad you figured out the problem. Make sure to do 50% a week, and you should be okay.

Salou fish, I'm also glad you found the problem with the bala shark, and it was both a wise move to do a pwc, and move the shark to another tank provided it has bacteria to care for the water...You can use prime to temp...(24 hrs) neutralize the ammonia into ammonium...just remember its is temporary fix. And I'm glad to know the gender so I may not call you a him...lol. Do you know anything about your water conditions from the municipal supply...such as does it contain chloramine or just chlorine and no ammonia? PP
