Cooling a Hot Pool

[rlanthony@excite.com]

I hooked the polaris fountain up last night. I run the filter from 4-10 PM and from 4-10 AM. The temp last night was 92. I will check this evening to see if any cooler. I will change the filter times to run longer at night to get some surface and evaporative cooling with the fountain. Don't have an aerator. We'll see.

Rick - I'd be very interested in whether or not the Polaris fountain helps. I live in the Dallas-area and as you know, we're going through a spell of 100+ degree days. The pool temp was 94F when I got in at 8pm last night. I think 94's just a little too warm.

Let us know how it works out for you!

I'm near Shreveport, so we're getting the same weather as you Dallas folks. I've been running my pump only at night and so far have managed to maintain no higher than 90 degree water. It helps too that the kids turn the slide on while they're swimming--the introduction of that much water actually will cool the pool by a couple of degrees over a couple hour period.

well you could always pump some water out and refill, I'm sure the tap water is cooler than the pool.

It would work, but in some areas (I believe Dallas is one), they have water restrictions that would make draining/refilling a problem. Also, depending on your fill water composition, draining and refilling can really mess with your chemical balance.

And, with the high temps that much of the country is having, it would only be a matter of days until the water temp was back up there again. So, it could be a short lived fix.

Well, there's full proof that Ben is totally AWOL - Duraleigh's post wouldn't have lasted more than 5 seconds and Duraleigh would now be permanently banned from Poolforum even though he has given years of insightful and extremely helpful advice to many a lost soul on this forum.

One thing that keeps coming to my mind about using a fountain is loss of water to evaporation - bearable if you have a water source to replenish from, not so bearable when you have to pay to truck your water in.

Burrying the hose would definitely help, however, in climates with frost (where hot water problems would likely be less prominent), it may cause an issue when it comes to draining the hose at year's end.

We've had clouds and cooler temps the last couple of days. So not much solar heat getting to the pool. When it was sunny I checked the temps it went from 92 to 89. Not much cooler. I will check the ph and alk this weekend to see if it is changing. I did run across a comercial mister device I'll see if I can find it again and post a link. It seems to be very similer to the device posted, but prebuilt. It was about 29.00 and hooked up to an eyeball socket. Compared to the forced air fan type at 2600.00 I think it may be worth a try. I have notice some more rapid water loss, not much but just about 10% more than normal for this time of year. Thanks for the input.

Contrary to Matt's suggestion of running the pump at night to mix the water I would suggest that maybe the opposite would work.

If the water is more or less stagnant, the hottest water will rise to the top. You can ofter feel this when you swim in stagnant water. Colder at the bottom.

So if you want to lose heat, maybe you should let it rise to the surface and cause more evaporation for cooling. Everyone I know says the greatest loss of heat when you're trying to get a pool warmer, is off the surface.
