Need a inexpensive way to cool the pond water. Phoenix AZ current temp HOT!!
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 |
I'd try some serious artifical shade. Depth is another option but not inexpensive. kathy :-) www.blogfromthebog.com this week ~ Mosquitoes! Run For Your Life! Pond 101 page for new pond keepers ~ http://hometown.aol.com/ka30p/myhomepage/garden.html |

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): http://www.animalworldnetwork.com/chforaq.html 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. http://www.drsfostersmith.com/pic/ar...id=434&aid=417 I hope this helps. Good luck. |

Depth isnt really going to help.. unless i could dig it about 10' deep
which I cant.. I am serious its 100degrees 24/7 for 3 months this time of year. the ground is sooo hot the tap water comming in the house is not very cold either this time of year. I have some Lillys now but not enough to cover the whole pond and I just put in 4 more plants yesterday... more lillys and some iris and something else.... By morning the water is 20 degrees cooler but by 2pm its very warm. What about that blue die for ponds? I have some of that. wonder if that would help at all. I dont like the look it gives but its liquid shade in a bottel. Chris |
Now thats a pond!!!! your pond is beautiful, very nice work.. Love the
look of the dick and boat house. Chris |

Thats what I have done in our hot tub on a few occassions when I wanted a cold tub more than a hot tub.......it works pretty good too. I would have to venture with a lots of shade is about the only resort unless your prepared to spend lots of money for a chiller unit. Around this paart its not uncommon for high temps either,,.How about a fine mist of water. I have heard others say a trickle tower has a chilling effect on water up to a certain point. Take some temp readings at the top and middle and bottom and you may be surprised the bottom strata is a lot cooler than you may think. Around my ponds edges the water this year has been in the mid 90's down to about 8 or 12 inches, however after that its a big change and hits the lower 80's, and at about 3 feet or so its in the 70's. I monitor my water temp from surface to 12 feet just for the heck of it usuing a bank of remote electronic thermometers and sensors that are permanently installed. Once I get past 8 or 9 feet the temp stays rather constant all year round...... More aeraton and shade would be a big help for your pond / fish On Fri, 24 Jun 2005 23:33:05 -0700, ~ janj JJsPond.us wrote: ===Take a few milk jugs. Fill with water. Cap and freeze.

If there is no natural shade how about using one of those "cheap" blue tarps and some timber (2*4s) as tent poles to rig a tent over part of the pond? With a little ingenuity you could provide shade for the pond and some for yourself next to the pond, then you could site out next to the water with your favorite tipple. ANO |
They make what is called Shade sails. They are a heavy duty nylon or
polyproplyene fabric made in the shape of a triangle. They are supported by using three poles and three stakes in the ground or tied off to other existing structures and tensioned. The triangle shape, and outer perimeter cable they have works better in windy condiitons than a square shape does as it allows any captive air under it to bleed off quick and not create as much lift and billow up as a square would. A lot of ponders on another forum speak very highly of them in giving them the needed shade for their ponds. A ready made 12 x 12 x 12 foot triangle shade sail is about $130......and all you need is a means to support it, usuing pipes wood posts or other structure. http://www.shadesails.com/newpage11.htm ============================================== Put some color in your cheeks...garden naked!

I live just a few miles from you (northern Phoenix), and I feel you're
overestimating the problem. My 'koi' pond is roughly the same size as yours, and I have never had a problem with the pond getting too hot for the fish. I DO have a lot of natural shade on the west side. Here are a few other suggestions. Home Depot and Lowes carry a polyester based UV resistant shade fabric. A 6' X 24' piece weights about 20 lbs. The stuff is tough, and very resistant to ripping. I use 4 side by side to keep my swimming pool shaded even in mid-day (great for the grandkids). You can make a very sturdy framework from 1" or 1 1/4" PVC pipe (make sure you anchor it securely for the monsoon season). The same places also sell lattice panels. The goldfish pond is shaded by a roof of them, with a trumpet vine growing on it. Again, no problems with overheating. One of the easiest solutions is some kind of fountain or waterfall. The cooling effect is significant, just make sure you have some way of replenishing the water lost to evaporation.

It has been a long time since I lived in AZ, (Tuscon, and Ajo) but back then
we cooled the house with what is called a swamp cooler, that worked on the basis of evaporation. Those things worked fine out there, but due to the high humidity in the east, they don't work at all. Evaporation is one of the best forms of refrigeration, and cheap to set up. Just get a fountain with relatively fine streams, and the water reentering the pond will be chilled. A waterfall would have a similar effect. Shade will prevent the pond from getting solar heating, but it will still try to get to the average ambient, day/night temperature, except for the cooling effect of evaporation. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Dude" wrote in message oups.com...

,,.How about a fine mist of water.
Which reminds me. Isn't AZ where they came up with those fine misters above a patio to keep it cool? Why not above and around the pond? ~ jan ~Power to the Porg, Flow On!~ |
Thanks PlainBill for informing me I dont know what hot water feels
like. "I live just a few miles from you (northern Phoenix), and I feel you're overestimating the problem." I also mentioned in my origianal post that I do have a waterfall, I also have a large airstone in the water to add extra O2. I also have two lines from my drip system that adds water to the pond twice a day. No drip head on the line just a straight piece of drip line so it comes out at full preasure. I took my large umbrella that goes in the ground by the pool and placed it next to the pond thismorning and that made a huge difference. The umbrella is about 5' in diameter so the shade it provides covers most of the water surface area. Chris |
Im not sure how a mister system will keep the pond water temp down? For
us humans the list mist of the water hitting our face feels good. But since the fish is already completly wet I dont think they can appreciate it the same way. Chris |

The only solution (and it is not necessarily an easy one) barring expensive refrigeration units .... Very, very, very expensive refrigeration units. For any pond of any reasonable size, no mortal can dream of affording such a thing. The prices would be well into the thousands $$. I did see an interesting home brew project where the guy built a heat exchanger deep, deep into the earth. He had a backhoe one day, and some extra time, so just went with it. This can work very well, and your only expense is the tubing and the pump. He was happy with it, but discovered later that he should have gone deeper. His area (AZ) has some pretty hot ground in summer, I guess. At a guess, doing something like building a heat exchanger underneath a shaded patios slab would be about optimal. Other than that, the only other solution I can think of is to buy a refrigeration unit (and like I said, they are expensive): Force additional evaporation, and the pond will cool some. Course, this means replacing the water. Which might be a plus is street water is cooler than the pond. And you have a way of getting the chlorine out quickly enough. No, heavy shading and making it nice and deep are about all you can do here. I missed the original message. However, if this is to protect koi, I believe it is proper to do temperature measurements across the depth of the pond. If the koi can escape to a moderate temperature on the bottom of the pond, I think they'll be okay. You might want to check with a local koi specialty place about that. IMPORTANT POINT: high water temp reduces the ability of the water to hold oxygen. Physical oxygenation techniques (bottom water pumping or an airstone) are called for in this situation. C// |
I have read about using a small dorm size fridge and converting it to cool the water in the pond. You can forget that, it will be a complete waste of labor. I would like to hear from other AZ ponders and know if you all are doing anything for cooling your pond temps. http://www.aquaticeco.com/index.cfm/...ories/ssid/370 That will work if it's big enough. Keep in mind that /most/ of these units are designed for home aquariums, and most home aquariums aren't 700 gallons. OTOH, if one wants to take a pond from 90 to say 78 or so, a smaller one might do it. I think one should probably do the math on the unit. Now, before you go off and stock your pond with expensive koi that you fall in love with, consider the consiquence if this chiller fails. At 90 degrees, your koi will probably die. I think you need to not have to worry about a critical failure here. Deep pond, some shade. That's a good "plan A". C// |

Just to jump in here, mine was 86 F at about 10:00 AM (maximum
sunlight on the pond). Estimating the temperature by sticking your hand in it is a waste of time. When it's 110, when you first stick your hand into a pond at 86 F it feels cold. Pull it out, let the evaporation chill it for a minute, stick it back in, the water feels hot.

A: Stop by the pool section in the garden center at Home Depot on
Thunderbird at I-17. Pick up a pool / spa thermometer. Without it you're only guessing at the temperature. B: While you're there, look on the opposite side of the aisle for sunscreen fabric.

Why not above and around the pond? ~ jan Evaporative coolers work incredibly well in AZ and NM. Last summer I was out in AZ, it was about 110F outside before a rainstorm came in, within minutes the air temp was about 60f. Unfortunately I don't think an evaporative cooler would work well in cooling a pond, not the way you described anyways, the transfer of heat from water to air is not very good, so a lot of water would be wasted for minimal cooling value. A better solution would be to run the water through some aluminum radiator coils, and to mist water over the radiator coils. Perhaps run a water line through the pond, before going to the sprinkler system, that would help, again minimally. I think probably the most practical solution would be to cut the tops off of a couple 2 liter soda bottles, fill it with water, then just dump the ice into the pond every morning, which really won't help, assuming my math is correct. Assuming 4L of ice, in a 90F (32C) 700 gal (2650 L) pond heat taken up to convert ice to 0c water 4 kg x 334 (kJ.kg-1) = 1336 kJ heat taken up to convert 0c water to ambient temp 4kg x 4.18 (kJ.kg-1. K-1)x 32 (º K) = 535.04 kJ kJ absorbed = 1336 + 535 kJ = 1871 temp drop of pond -1871 kJ = 2650kg x 4.18 (kJ.kg-1. K-1)x N(º K) = .16 ºC or about 3 ºF Seems to me to be an awful lot of work for such minimal gains. |
A quick Google on evaporative cooling turned up the following.
http://www.consumerenergycenter.org/...e_coolers.html It states that evaporative cools in dry atmospher can cool the hot air by as much as 30 degrees. The plus is that they use much less engery that a AC unit. It would seem one would need a evaporative cooler to chill air then an air/water heat exchanger to cool the pond water. It sounds doable. Up here in British Columbia I dont have to worry about the pond getting too hot - especially with the summer we are having.

Perhaps run a water line through the pond,= before going to the sprinkler system, that would help, again minimally. If those aluminum radiator coils were buried somewhere cool, you'd have a heat exchanger, and it would be effective. The challenge will be that the ground gets pretty hot in AZ in summer. So finding that cool spot will be work, and the digging will be deep. C// |

A quick Google on evaporative cooling turned up the following. http://www.consumerenergycenter.org/...e_coolers.html It states that evaporative cools in dry atmospher can cool the hot air by as much as 30 degrees. The plus is that they use much less engery that a AC unit. It would seem one would need a evaporative cooler to chill air then an air/water heat exchanger to cool the pond water. It sounds doable. Not necessarily. Any fountain is going to work as an evaporative cooling mechanism - the finer the spray the more effective (but also, the more water the pond loses by both evaporation and wind-drift). If those aluminum radiator coils were buried somewhere cool, you'd have a heat exchanger, and it would be effective. The challenge will be that the ground gets pretty hot in AZ in summer. So finding that cool spot will be work, and the digging will be deep. Again, that's for a "perfect" solution, but you don't need refrigeration, just enough cooling to keep the pond at a nice temperature. I don't know Arizona, but you only need to be down a couple of feet to be significantly cooler than daytime air. Basically, if you can get the heat exchanger into any soil that stays under 80F, you should be cooling the water below the danger zone for your fish. -- derek |
A: Stop by the pool section in the garden center at Home Depot on Thunderbird at I-17. Pick up a pool / spa thermometer. Without it you're only guessing at the temperature. One could not have better advice. C// |

I got a thermometer from Petsmart yesterday. its 5:55 am now and the
pond is 78degrees. Ill check it at 1pm and see again. I added 4 more comets and4 more shubunkins yesterday and about 30 rosies. I also just ordered a bunch of 72 stems of anacharis. Chris |
I live in the south so i have to have a lot of shade also. I built a
"terraza" over my pond..... BTW i live close to the gulf so it also keeps the big brown pelicans and herons away...below are some pics;-) http://community-1.webtv.net/MATRIXJ...TLE/page4.html |
