Is it safe to use prime if there is no ammonia in the water? I have an ammonia test kit (API) and it shows number around 1. But the fish are all doing fine. I have 10 gallon tank with 2 guppies in it for now. I have read that it might be ammonium which i think its safe for fish. But i want to make sure I harm no fish. So my question again is, is it safe to use prime even though there is no ammonia or chlorine in the water?
Prime is just a simple dechlorinator, that's all. It does nothing for ammonia as tests and professionals prove on the web. Only need it when you add water to your tank to neutralize chlorine/chloramine.
