I am having a serious problem. Both of my tanks, which were cycled and ready to go, are now reading:
I just tested my tap water and it's:
I've lost one guppy out of one tank, but all of the rest of the fish are doing just fine. I am using Prime and Stability with each water change. I've cut down on feeding to every 3rd day, thinking that maybe I was overfeeding even though there was never food left at the bottom. Water is crystal clear. The man at my LFS gave me Seachem Neutral Regulator to adjust my params, but no matter how many water changes I do, I can't get the ammonia down to raise the pH, GH, KH. I know that with the pH so low, the nitrifying bacteria can't do their job. I also know that with the pH so low the ammonia isn't in its toxic form. I have a Seachem ammonia alert hanging in one of the tanks and it shows "safe" but I know I need to change things. What do I do?
