Just a quick update: I did the 50% water change. While I was looking closer at my comet, I noticed that a very fine edge of all of his fins are black. It's a very small part of the edge, I have to be within a foot away to see it. I have an excellent book written by Dr. Erik Johnson, and he states that black edging on fins is not uncommon if there has been a water quality problem. It may actually be a sign of healing of the fish's epidermis. So, the black edges are new and maybe that means that the ammolock is helping with the ammonia (until my pond cycles)and the water quality is getting better. Maybe that is all the spots are on the gill covers too. My fish is eating and swimming very actively again today. Do you think I should still put him through picking him up to look closely or just continue to watch him? I'll continue doing water changes while I wait for my filter to work. My nitrites again today were 0 and my nitrates were 20. Thanks so far for all of your advice!
