OK - I used a capful and a half to dechlorinate my tank. How long should I wait before I put in my ammonia so that the Prime doesn't detoxify or kill it or whatever. You know, when Prime would have no affect on it. AND... how much ammonia should I start off using in a 55 gallon tank, and how long after should I wait before I test my ammonia level? How long for it to circulate to get a true reading? An hour or what?
