I live in Peoria AZ and from mid June till mid Sept its over 100
degrees every day even at 3am its 100. My poor fish have to endure
extreem pond temps, I dont know exactly what the pond temp is but I
would guess about 90 degrees. I just got done doubling the size of it.
I would guess it's about 700 gal give or take.
1250gph pump to my UV filter, Bio Filter, & water fall. Filtration and
airiation is pretty good but the fish hide during the day trying to
stay out of the Sun... Good luck out here. I have some pigmy palms to
the back of the pond and the pond has the block wall fence on two sides
of it and I have a Ficus tree in front of it but the tree is still
young and not big enough to provide any shade yet. On top of everything
my house faces east west so the back yard gets direct son for about 6
hours.
I have read about using a small dorm size fridge and converting it to
cool the water in the pond. I would like to hear from other AZ ponders
and know if you all are doing anything for cooling your pond temps.

Thanks,
Chris

The only solution (and it is not necessarily an easy one) barring expensive
refrigeration units would be to dig the pond deeper, so that it will be
better insulated by the earth, and to completely shade it from the sun.
Other than that, the only other solution I can think of is to buy a
refrigeration unit (and like I said, they are expensive):

Those listed on this web page, however, will likely not help you much if
your pond is very large. I just posted the link to give you an idea of how
expensive these things are. But here is another web page for ponders that
might give you some ideas on how to cool your pond water. It is important
to make sure that the water doesn't get too warm, as O2 levels will plunge
as the water temperature rises.

I hope this helps. Good luck.
