I test my ammonia levels every other day and they continue to be high. I do a partial water change and put in th e recommended amount of ammonia neutrilizer. I check my levels a couple of days after still high..so i repeat the process of doing a partial water change. My ph is a 7.0 and my nitrites & nitrates are normal. Doing a total water change is out of the question so I do not have a spare tank for my fish. Any advice on how to get my ammonia levels down would be helpful. FYI I used Terta safestart to start the cycle.
