Keep reading conflicting threads about ADA Amazonia. I have ordered a couple of bags and was intending to swap the coral substrate in my tank with this. What I was going to do was keep the original water is large buckets keeping the fish in one bucket with a heater in it while I replaced the old substrate with the new. Now some posts are saying this will be ok and other are saying the new added ammonia will harm my fish. Can someone advise me if what I intend to do will be ok :?
