I have been battling my ammonia problem for about a week. I did daily water changes of 50% and added stress coat and I was still reading .25 so I got smart and tested my tap water. Sure enough my tap water is reading .25! I have well with a whole house filtration and a softener. Should I consider buying bottled water or use a product like AmQuel? I know which one is better for my pocketbook but which one would be better for my fish?
