Hi Stan, My levels were closer to .25ppm. My guess is that if you continue to put water in the tank that contains ammonia, it will never clear out completely. I think that any level of ammonia is not good for fish health. I'd certainly welcome other thoughts. I fortunately had recently purchased a gravity fed water filtration system for my drinking water. It uses ceramic filters and filters out ammonia, chlorine, nitrAtres, nitrItes, etc....
