To all that helped out. I consulted a few experts- or at least people in the business around here. The suggestion was to empty the pond clean it and re-establish. After 12 hours at hard labor on Saturday it was clean.In cleaning the deep center area I found a fish under a rock that was dead for some time- plus all the junk and leaves. I now have a large gravel bet about 4" bottom and have put the fish back in but this time we counted the amount-it turns out we still have 178 fish. I would have never guessed that amount. We have added the Bio Boost to get things going but the store told me not to use anything else-on the container, it says to remove all chlorine from water. Will I have to start again with bacteria or should I put some clorine, chloramine remover in now.
