small pond - I respect everything your doing and wish more of our youth would follow your example. I can't help you with your fish right now (not qualified to answer your question) but I have a few things that I might be able to do for you to prevent it from happening in the future.
How many gallons or cubic feet is your pond? Do you get sun light down to the pond? If so, how many hours a day?
My pond is 18,000 gallons when full but it is currently about 4 inches low so it should be about 15,000 gallons. the pond is completely in the shade so it gets very minimal sun light.
