All fish are scouted forman that sucks
Should a make a 15 gallon water change and add some prime tonigth or should I let it go down
I would stop looking to dump solutions into the tank. I would just do weekly water changes FAITHFULLY for the next 8 weeks and monitor.
I also see elevation in your ammonia which tells me you are in cycle. Please test for NITRITES. With your ammonia that high and zero nitrates, I'd bet you will get a nitrite reading.
What may help... try adding some bottled bacteria to the tank. With the information you've posted, I think your nitrifying bacteria colony is too small to handle the bio load. A drop in ammonia is an indication that your nitrifying bacteria colony is growing.
man that sucks
