need help on cooling a pond?

[hankn]

Daytime temperature here is usually above 100F for most of July and August with no break. No rain, no clouds. My 600G pond (max depth of about 2.7', with a waterfall), without shade (and about 8 hours of direct sunlight per day) runs at 84F and seems to be fine.

If need be, I was considering just taking a block of ice and dropping it in the middle of the pond just to cool it down a bit. No idea what that would do to the fish, though.

Don't think your going to need any cooling help at that depth. Just keep it shaded, naturally or artificially.

Did a hole (post hole diggers) where the pond is going and to the depth of the pond fill with water and measure the temp over a 24hr period. if temp is to high did another 2ft down and test again. You may need to did a same deep hole in the pond and put a small pump in to circulate the cooler water on the bottom,

Floating a couple of 2ltr bottles with water frozen in them will work better than the cooler.

i would do a waterfall or a fountain to increase oxygen in the water

I built ponds in Phoenix AZ for a lot of years and delt with the heat problem first hand. Depth is your friend as far as a stable temp goes. An extra foot in depth really helps out.

To figure out if you need any extra cooling then give this a try. Take your usual summer daytime temperiture (high) and then average it with your low.

At 4 feet deep...water takes a LONG time to change temperiture but it WILL change so the average is importiant. In Px the AVERAGE would sometimes hit over 100 for months at a time. Ariation (fountians and waterfalls) can only drop the temperiture down to low ambiant.

Most fish learn to tolerate it but breed a LOT better in lower temps. A low cost chiller is fairly simple to build out of a smaller secound hand refrigerator and a long coil (The longer the better) of vinal tubing.

well i ahve some muskie and i've been told to keep coller then that and i feel thats to hot.

If you want. It wont hurt the fish. Just be reasonable about it. I have seen fish cooled like that and it works fine.

 

[muckieman]

ok thanks but i think they would live longer in colder waters(well at least thats what i heard) and thats all i want to have them live long and be happy(bad speller)

Take a small chest freezer , drill a inlet and outlet hole and you got yourself a cheap thermostatically controlled chiller. Add some filter floss and you could supplement the mechanical filtration as well
