Hi! I'm a newbie doing a fishless cycle at the moment, but I have a question about the 0.25 to 0.50 ppm of ammonia that's in my tap water. (The amount of ammonia from the tap varies a little each time I test it.) Since starting the fishless cycle I've used Stress Coat to dechlorinate the water, but when the cycle's complete and I actually get some fish, I was going to use Seachem's Prime instead. I bought a bottle of it recently and today I tested a gallon of tap water that I dechlorinated first with Prime and using my API liquid ammonia test kit, it gave a reading of 0.25 ppm. If Prime removes ammonia as it says it does on the bottle, then why does the dechlorinated water still have ammonia in it afterwards? Shouldn't it be zero? Is there something else I'll have to add to the tank during each WC to eliminate the ammonia from the tap? Thanks for the help!
