Yesterday the ph was 8.0 today it is 7.8 and the two remaining fish
seem fine.
She only had tests for ph and Ammonia. No roots or any overhangs,
seems like all the larger fish died, I suppose the dieoff of the algae
didn't help the 02 in the water either. Unbelievable to see that much
algae die off literally overnight....then to loose the fish. She
hadn't checked the pH yet this year, so we had no previous number to
compare. Thanks for everyones help. Maureen

Roy hit the nail on the head, large fish dying first, usually means low O2.

I would recommend those who live in areas of much rainfall have the test to
measure KH. Rain water has no buffering, and supplemental treatments need
to be added unless other means are in the ponds.

Okay, help me out RPers, was it limestone or crush oyster shells that was
recommended as a slower method than baking soda to increase buffering?
