Heat and Water Temps ??

Any good tips on how to help bring down water temps of 80 degrees.
The heat is on, here in OH-- the pond was at 78 degrees yesterday and 81
degrees today.

I've been misting the pond for 3 or 4 hours every evening and topping it
off with cold water every other day.

The pond is about 2200 gals. has a waterfall and is 2/3rds covered with
lilies, lettuce and water hyacinth. It has a 2 foot wide bridge over it
that offers some more shade.
So far the koi and goldfish seem Ok-- but we are expecting 3 more days
in the mid to high 90's and I'm getting worried.

Those temps aren't bad for koi or goldfish, now if you have trout, that
could be a problem.

We had 7 days over 100+, one of which was 112F. Koi ponds got up to 84F,
goldfish lily pond got up to 88F. Everyone made it thru fine. Except I
can't find 2 goldfish. I was in the pond today searching, no bodies, I
think I had a Kingfisher visit (damn!) one was a $35 panda moor male. :-(
Make sure you have lots of aeration, fountain and/or waterfall going. Don't
feed over 84F. Your bio-bugs are not working well at those higher temps.

I think you are in little danger of overheating, but in case things
get worse and the fish begin to gulp at the surface. The oxygen
content of the water is of greatest concern. I added an Oase pump
last spring and some use aquarium pumps to add oxygen to the water,
but here is an emergency measu

It's even hotter here in middle TN. We have old white sheets and curtains
covering 1/3 the top of the above ground ponds. They rest on the protective
netting. Clothespins hold them in place. The inground ponds don't get as
warm. The water was over 90 the other day but the koi, rosy reds and GF are
tolerating it well.

I would make sure there's good water circulation and aeration. They should
be ok if mine survive water in the 90s. :-)

It could have been a snake or bullfrog as motion sprayers don't deter them
at all.

I am so grateful, thank you all for relieving a major part of my heat
related stress. It's been in the mid to high 90's here, for the last 4
days with heat indexs of 100 to 105. No relief expected before Fri.

After the heron attack in June, I don't think I could have stood losing
any more fish from the pond.

We have the same problem. It's already 95 here and very humid. I looked at
the floating thermometers last night and the water was at 92F-93F in most of
the 680g breeding tanks. The fish were fine. :-)

any more fish from the pond.

At one time we were losing several fish a week, then a day. We finally gave
in and bought those thin hard-to-see black bird nets and netted everything.
No more losses to snapping turtles, huge bullfrogs and water snakes,
kingfishers and herons.

Take advantage of basic chemistry. Use water in an alternate form. Namely
ice. It takes a lot of heat energy to melt ice. Heat energy that can come
from the pond.

For a large enough pond, cut the top off a 2 liter soda bottle, fill it
about 3/4 with water, then freeze it over night.
Then put the giant ice cube in the top of the waterfall. Assuming my math is
correct, each 2L bottle of ice will lower a 2000 gal pond by 0.2F, and
further assuming that the heat energy only comes from the pond, and not the
air above the pond.

10lb blocks of ice is about 4.5L of ice. Placed in the waterfall stream, it
should do a good job of evenly spreading out the cooler water, instead of
creating a cold spot in the pond which could shock the fish.

Math:
Heat 2L of ice @ -5C
2000mL * 5C * .5cal/CmL = 5000 calories
Melt 2L of ice
2000mL * 80cal/mL = 160000 calories
Heat 2L of ice water to 26.6C (80F)
2000mL * 1 cal/CmL * 26.6C = 53200 calories

Cool 2000 gal (7570L) pond by N degrees
7570L*1000mL/L * 1cal/mL * N = 218200 calories
N = 0.028C ~= 0.03C

Good idea. I always figured one would put them bobbing in the pond.

Be sure and dechlor the water before freezing, or just leave in bottle. It
might even melt a bit slower in a sealed bottle. ~ jan

That's cool!
