I am a newbie to the forum. i live in the Houston area and purchased a 55 gallon freshwater tank. Then I tested my tapwater and it is positive for nitrite and ammonia. I treated some tap water with a conditioner (Kent Fresh Start) and one hour later, the water was still positive for nitrite! Will I have to use RO water? I'd rather not, given the hassle, plus the need to add back minerals to the RO water. I'm concerned that even if I do get rid of the tap water ammonia and nitrite through cycling, I will stress the fish with each water change adding the bad tap water. Please help. Thanks
