Chandler1, your 1st issue with water clarity was due to suspended clay particles. Rainman walked you thru the correct process for clearing it. The decreased clarity now is due to the phytoplankton, or floating algae(the good kind for a fish pond) that is the beginning of the food chain. It is developing due to the decreased turbidity. Please dont add any more alum to your pond. It is clear of suspended particles. You needed to have enough lime on hand to neutralize the alum to prevent fish stress due to rapidly changing ph. Adding well water, which is inherently low in O2, to a small pond without spraying it into the air to oxygenate it, can cause low dissolved oxygen and also stress the fish. Your pond appears to be in a good natural state of fertility for this time of year. I am sorry for your fish loss; consider that they may not have been healthy and that the remaining ones will be better off. Goldfish are usually very hardy, so losing a few is unusual. Most people that want good fishing ponds avoid goldfish like the plague. It is hard for the small and beautiful pond to be all things. It looks like time to sit back and enjoy the fruits of your obviously hard labor of love. Good luck and good fishin'.
