I'm curious as I was reading that the treatments can lower the alkalinity/hardness of the water. That likely compounded if you've had a big rain event adding a lot of new water to the pond.

What I've seen on my pond is that after a rain my standard tests of PH and Alk/Hardness fluctuate quite a bit and it takes a week or so before they get back to normal. Throw in high water temps (summer) and a lower ability of the water to hold 02, I'd be really cautious about treating again right now. That's just me though.....I have no experience in pond treatments with alum/hydrated lime.
