Hypo question concerning ammonia?


I have a 10 gal QT with a yellow tang. I hoped to have him in my 120 by now, but black ick and possible brook surfaced. So, I gave him formalin baths and started lowering SG for Hypo. The SG has been at 1.009 for about a week now, but the ammonia is starting to rise. I keep changing the water out daily and assume I'm increasing the problem and lowering the bacteria, but do not know what else to do. The ammonia gets up to .5. The fish seems fine, but I'm afraid to leave him very long. I've been taking water out of my 120 and adding fresh water to keep SG at 1.009.
Is there anything else I can do? I've seen some type of bacteria boost at the pet store (not sure exactly what it's called). It comes in a packet and is to be added to the water. Will this help?

Consider using a product like Amquel plus to neutralize the ammonia and other nitrogen cycle products until the biologic bacteria catch up and continue your water changes.
