All of the fish in the pond are now dead.

I never want to do this again.

A thought just struck me. I see you are in Georgia. Could all the crazy rain have had anything to do with what happened? Perhaps runoff from ground treated with lawn chemicals?

 

[420benz]

No Because the pond is much higher than the lawn.

How high was high (the ammonia) and for how long? This is a very toxic chemical and conceivably it caused enough internal tissue damage to result in eventual death - in spite of the neutralizer added later. Ultimately, it may not be known what exactly happened - so the place to start I think is to re assess your whole set up & whether or not its adequate for size of pond and number of fish.

One thing that puzzles me is what all these gaps are, where the fish were hiding - you might want to seal those off somehow. If water and oxygen is not freely circulating thoughout the pond you could have dead zones which harbor bad bacteria - not good.

There are sooo many small gaps that plugging them is not Feasible.

No need to worry about the spaces between rocks @420benz . I think @Big Red Comet just misunderstood what you meant when you said you were finding dead fish in the spaces.

Great overall advice as usual @Lisak1 .
Ammonia binders are only effective for 24 - 48 hours after application. After that they lose all effectiveness.

 

[420benz]

Good advice as usual is correct. Thanks
