My 29 gallon tank is two weeks old & I've been battling ammonia since day 1. I have done 4 water changes using BOTTLED WATER, which I tested before putting in the tank. The ammonia of the bottled water was 0. Yesterday I did a 75-80% water change using bottled water & the ammonia is still at 8 !!!!! Where is this ammonia coming from? Also yesterday I restarted the tank using Seachem Prime & Seachem Stability. I have two very small blood parrots & a very small cat fish in there. I’ve also tried using Ammo Lock & Ammo Chips plus water changes. I’m at my wit’s end!!! Yesterday I also cleaned out the filter & put in a new cartridge & cleaned the ornaments & plants. How can it have an ammonia of 8 with new bottled water in it? I’m losing my mind!!!
