I'm doing a fish in cycle, it's been a couple weeks now. Typically my ammonia has been anywhere between .25-.5 and nitrites are 0 and nitrates are at 5. Last night, for fun I decided to test my husbands pond and our tap water. Our tap water had .25 ammonia. So I'm wondering how this effects my cycle. Obviously water changes aren't going to bring my ammonia down to 0. But does that mean when my tank tests .25 it's actually 0? Or since I don't usually test right after a water change, should there be enough bacteria in my tank to handle the ammonia in my water & from the fish so I should keep going until it's testing 0 anyways. I'm confused!
