Hey guys so my 10 gallon mixed reef is about 6 month old. Live stock includes cuc, 2 little clowns, and a little bit of everything when it comes to coral softies sps and some euphillia. Everything is happy coral included. Anyway added rock and moved some stuff on Sunday and I found .50 ammonia the past 2 days. Did water change it's still there. It's a api saltwater master kit. Is it a faulty kit sinse my corals are fine or what should I do?! Thanks for any help I have all my levels if needed but I didn't think they where necessary to post.
