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. |

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 http://tinyurl.com/e9h32 Regards, Hal |

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. 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. I would make sure there's good water circulation and aeration. They should be ok if mine survive water in the 90s. :-) -- KL.... Frugal ponding since 1995. My Pond & Aquarium Pages: http://tinyurl.com/9do58 ~~~~ }((((* ~~~ }{{{{(ö ~~~~ }((((({* |

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

Heat and Water Temps ? (Thank You 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. Bette |

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. 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. :-) After the heron attack in June, I don't think I could have stood losing 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. -- KL....

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 |

It might even melt a bit slower in a sealed bottle. ~ jan ----------------- Also ponding troll free at: http://groups.google.com/group/The-Freshwater-Aquarium |

But I honestly don't think 2L of slightly chlorinated tap water is going to be much of a danger when it's diluted with 7570L of pond water. 2L makes about 0.02% of the pond's volume. Of that, how much of the original ice water is chlorine? We're talking about such a small fraction, it's not worth the hassle. -S |

actually the phase transition from ice to water is 80 calories per gram whereas the
transition from liquid to gas is 540 calories per gram. http://weloveteaching.com/fall2005/m...of_matter.html better to spritz the water up into the air and what falls back is going to be a lot cooler. best is shade cloth, like 70% or lilies that float and block the sun. actually, a piece of styrofoam that blocks the sun works too.

Ingrid ==================== 2 x 4' sheets of white Styrofoam can be found at any Home Depot or Lowe's and last for years. We use the old bedsheets suspended above the water because they don't block gas exchange at the water surface as floating Styrofoam sheets would. -- KL.... Frugal ponding since 1995.

Ingrid That assumes that the humidity level is low enough to support evaporative cooling. Presumably the waterfall and other water circulation features already maximize the evaporative cooling potential. Reminds me of what one of my profs used to say. Try both, see what happens, then report back to us. -S |
