I’m almost certain it is ammonia, I’m useing the fluval master kit, how would I be able to drop ammonia levels fast? I have seachem products stability, prime, amgaurd. Wish I had gotten them before adding the fish I have dosed with a cap full of prime and Amgaurd yesterday
Prime will help, as will water changes. However, never use Prime with copper medications, it can break the copper/amine bond and release toxic amounts of free copper.
What levels of ammonia are you seeing with your test?
