With all my problems with Ammonia in my 55 gallon tank now I find that I have .50ppm Ammonia in my tap water. I dont know if this is bad or not but as I am trying to get my levels all stable and ammonia is constantly high if this is a big part of my problem. I have since posting here last lost all 5 cherry barbs and 2 of my 4 black mollies. The 2 danios are still looking good as well as the gold platys. I have not added anymore yet since I cant seem to get this tank stabilized. Any more helpfull hints? Have tried the daily water changes I use a rock vac. I also use prime and stresszyme.
