My pond in Florida last night was 84 degrees. I put my well water in and got it to 79 degrees. The comet gold fish and the koi fish all seemed to be fine.

Denny- This thread is 9 years old but as summer is here for some of us, ponds are heating up. Extra aeration is good and I always cut back on feeding my koi if the water temp get close to 90.
