2017 is not starting off well. Came back from visiting family to find that some clowns were gone. Via another thread it was contributed to clown aggression. Now I've lost several fish. When tested on December 31st the ammonia was zero. When tested on January 3rd the ammonia was .04 (tested twice). I'm betting that I screwed the pooch on the 12/31 test. Otherwise it means there was a large spike in three days. I've temporarily added a canister with ammonia remover via the manifold. The ammonia is now ready zero (tested twice).
I wish I knew what caused the ammonia spike.
