Even with shade from the lilies and other plants on the south side of the
ponds the water is now 84F to 86F. One older koi developed "dropsy" and
died, but probably not from the heat. Last summer the water went into the
90s. The filters need weekly cleanings even with the use of the expensive
koi food.
