Hello everyone I'm new this and need help!! I have a 60 gallon tank that contains 2 clown fish, 1 blenny, and 5 peppermint shrimp. Also 2 live rocks and 2 dry live rocks. I use the API test kit and according to that my ammonia level is through the roof. My fish seem fine and don't seem to be stressed. I've done 2 50% water changes and the ammonia level won't budge......i test the water before putting it in the tank and it's of course at 0. Once I put it in the tank and test it I'm getting very high ammonia levels I use treated tap water in my water changes can someone plz help me
