Does anyone know if there are any pond pumps that also refrigerate the water
that passes through it? It's getting really hot here in the Sacramento Valley.
The pond got to 80 today and could get hotter. Throwing the contents of the ice
maker into the pond only lowers the temperature by one degree. Not really much
help.

Here is an idea that comes from a friend who drinks a lot of beer. Take a
strong cooler (tuperware or better), and coil rubber tubing into it, then pack
the cooler tightly with crushed ice. Connect the pump to the tubing and run the
tubing into the pond. The ice will stay frozen longer, and it should help cool
down the pond (depending on how big the pond is). You can upscale this idea as
needed. It works great for beer. Try it and see if it will work for the pond.
You should also reduce the flow rate somewhat to allow the water more time to
cool down in the tubing. Copper tubing works better as a heat exchanger, but
then you have to buy a pipe bender and do all the bending at all the right
places in order to coil the pipe into the cooler. If it works, you might
consider permanently installing intake and outtake connectors for the
pipe/tubing through the cooler so that the cooler can remain sealed. Sorry,
it's the best that I can do for now. Good luck, and keep us posted on your
eventual solution. You should also try to provide as much shading for the pond
as possible (just don't cover it with black plastic).

Just to give you an idea of what one of these beer coolers look like, take a
look at the coolers on this web site:

http://www.kegworld.com/jockybox.htm

You can see how much one would cost if you purchased it. But you can build one
cheaply if you are enterprising enough.

TT is a decent evaporative cooler. Do you have 1 yet?

Place a block of ice in the waterfall, rather then just having a bunch of
ice cubes float around the pond. Cold water does not mix very well with warm
water, because of differing densities. Letting the ice melt slowly, by
cooling lots of water a little bit, it helps evenly cool the water.

For an experiment, fill up 2 glasses, one with hot water, the other with
cold water. Then add a drop of cold food coloring to each. You'll see that
the cold food coloring just sits in the glass of hot water and doesn't mix
very well (unless you stir it)

It also should be noted that it takes a lot of energy to cool water,
naturally lots of energy means lots of money. Assuming my math is correct,
if you have a 1200 gal pond, lowering it 1 degree in 1 hour will mean
disappating 18026.7 BTU in an hour. Assuming that you have a 100% efficent
cooling system, that would mean consuming 5.3 kilowatts/hour. Let's further
assume you run this cooling system for 5 hrs a day, to cool it down 5
degrees a day. Since this would be peak rates, that's 36c/kWh * 5.3 kWh * 5
hrs = $9.54/day.

I've made some fairly generious assumptions here, so it would not surprise
me if a real world set up cost $12/day or more to operate.

You can purchase 'shade cloth' from many industrial supply stores and it comes
in many colors, lighter colors are better than darker ones or black. Have a
few tie-off points and possibly some support if it's a huge pond and simply
slide the cloth over your pond on the really hot days. You could do it a foot
over the water or 8 feet up so you could still enjoy the pond.

Ice and cooling systems are nice, but EXPENSIVE and inefficient. You're best
bet is to keep the water from getting that HOT as opposed to trying to cool
it.

For the longer term, plant some good shade trees on the side of your pond
where the sun comes from the most and cover more of your pond with floating
plants to shade it.

If money and the planet's resources are of no concern to you you can simply
let your garden hose run into the pond and let the water go down your
overflow.... tap water is normally around 50 degrees.

Do you have waterfalls, sprayers, spitters and floating plants?

Might want to get familiar with Doc Johnson's article on "Hydrogen
Peroxide For Dissolved Oxygen."
http://1-2-66-3456.notlong.com
He also has several articles about oxygen in the water, just do a
search for oxygen on his site.

I'm in Southcentral TX where the pond water
gets over 90 degrees, and that's in the shade
(shade cloth set-up - see below).

My solution: Lots of plants, low fish stocking,
shade (already mentioned), aeration and/or
filtration. I do the latter only on the pond with
the goldfish and so far haven't seen any problems
with any of my ponds. And mine are small -
ranging from 110 gallons to about 200 gallons,
so higher temps can really have an effect.

Also avoid feeding during the heat of the day
when oxygen levels are lower. And/or feed less,
like every other day.

This is excellent advice, and one I've taken
with my ponds. The shade cloth is very strong,
too, and if well attached with some slits cut in
it, holds up to fairly strong winds, as from
thunderstorms.

Problem with this advice is if the original
poster's tap water contains chlorine or, worse
(for fish), chloramines, such advice will
kill the fish. You can of course add water
treatment (Prime, for example) while adding
tap water, which is what I do, but that's not
going to work if he's replacing the entire
pond water.

I am assuming that you have a low humidity, and as such a swamp cooler will
do some cooling in your area. They don't do much around here with the high
humidity. You could build a modified swamp cooler, using media pad, a fan,
and a water pump to spray the water onto the media pad. Evaporation is a
very efficient means of cooling water.

Wow! Thanks for all the great advice.

The pond is around 1,000 - 1,200 gals with a 3600 gph pump. The return is a
3 inch rubber tube buried under a few inches of dirt. Over that there is a few
hundred pounds (no kidding) of rocks. The waterfall is about 6 feet above the
pond level with 6 tiers. The pump in the skimmer goes straight into the return
tube. There are 13 adult goldfish in the pond with about another 10 fry (and
counting) swimming around with the others. (They haven't taken on a gold color
yet, though you can just see hints of it now).
Today, the water got to 82 degrees, which seems a bit too hot. From what I've
read, the highest water temp for goldfish is around 76 - 78.
Right now the pond has no shade. There are water plants that provide some
shade but not much.
Sounds like the best thing to do is set up a light colored tarp to shade part
of the pond. Now I've just got to figure out how to do that.
Thanks again.

Building an evaporative water cooling tower might help a little. This is how
i would build one, though the benefits maybe marginal. Build a brick box,
with a hollow center, with a window near the top on one side, and the bottom
on the other side. Both windows need to be covered with a media pad, but put
a fan on the side of the top window, set at a low speed, you want to cool
the chamber, not create a wind tunnel.

Inside the chamber, have the water flow through metal pipes, to create a
radiator, then return the cooled water back to the pond. As I said in my
previous post, you'll have a lot of heat energy to dissipate to make
substantially cool the pond.

Unfortunately I don't know how to estimate the cooling abilities of a
evaporative cooling tower, to see if it's even worth it. I suspect the
evaporation rate from the pond does more then a cooling tower could.

Hi,
Goldfish can take 85 degrees without problem as long as the changes are
gradual and there is sufficient oxygen. Get an aerator and another lily.
There are also heat exchangers that can be buried that can modify the temp
somewhat (expensive).
HTH, -_- how
no NEWS is good for a reply

Bill - I forget where you live but here, the afternoon
and early evening hours are the absolute worst for
heat. When I was still doing the temp shade thing, I
made sure to position the shade contraption to
shade the pond from about noon on, not worrying
about morning hours.

I would think anything temporary would do for
now, just to keep your fish healthy. Eventually
you can work on somethig more permanent -
and more attractive.
