Ways to lower water temperature?

[sharpysharp]

We have had our 16' X 48" intec pool setup now for about two weeks and the temperature us already 90+ degrees in the evenings.... What is the best way to lower that temp without having to replace most of the water?

I know why it's getting so hot, the previous homeowner had a large 24' AGP on a 26' concrete slab, so now there's roughly 10' of concrete on either side just soaking up all that sun and the transferring it to the pool water....

Any ideas???

Set up a sprinkler system so you aerate the water. Use some PVC to connect to your return jets that spray the water up in the air

Aerate, especially at night
I doubt that the concrete is causing it
Cover when not being used and uncover at night

I wouldn't cover the pool at all as that is just retaining Heat by reducing evaporation

String up a sunshade. A few eyebolts (maybe) to the eaves, some rope, and a cheap tarp from Harbor Freight and you're in business. If you're a long way from the house and/or no trees nearby, I'm out of ideas.

But it would stop solar gain providing it’s not a solar cover

Even a solar cover does not do much to change the amount of heat the sun add to the pool. The covers biggest influences reduced evaporation and thus heat retention

We have a pool that is smaller than yours and I found a solar powered water fountain for it, makes a huge difference. Was less than $20 on Amazon

Here is another one what fits into a return

I find my thermal cover keeps the heat in and out inside my enclosure which is like a greenhouse in the summer

That one is great! Am putting it on my buy list for our new pool!

I had made a fountain last year for our smaller pool, but it made zeri difference..... I'll experiment around with some sunshade ideas

I'm finding a few things on youtube with plans. Seems relatively straight forward if you're comfortable with PVC...and who isn't?!?! My questions are: with all of the evaporation taking place to cool, anyone have experience with water/chemical loss through excessive evaporation? Any concerns about wrecking return plumbing by removing and modifying the outlets/eyeballs? IF it ever decides to stop raining in Georgia our pool gets in the 90's and I'm interested in trying to DIY one of these. https://www.youtube.com/watch?v=8Lvstuft-dk and https://www.youtube.com/watch?v=v04DcdpLU5Q I like the first one better.

Well I finally got my temps under 90 degrees! In conjunction with mid 90s outside temperature and my homemade fountain I'm at 86 degrees!!!

Just keep an eye on pH. Aeration tends to raise pH.

 

[sharpysharp]

That's good to know! Thanks

pH will rise so better have some MA on hand...

i decided this past weekend that i would do a test on my pool. i kept my solar cover on all day until we got into the pool at 8pm. i checked the temp when i got up on Saturday morning and the pool temp was 86 degrees. Saturday the temps got up to around 95 here and humidity index was 104. when i took the cover off at 8pm, the pool temp was 94 degrees. i know there are some people that believe that the solar cover does not do much other than help hold temps in over night. i am a believer that the solar covers actually DO help to heat up a pool. needless to say we had to run the fountain all night that night to get the pool temp back down to bearable conditions. letting the fountain run that long i ended up having to put in 16oz of MA to get the pH back down.

The issue is you can't prove that the cover added more heat, rather than just retaining heat that would have been lost to evaporation during the day.
No way to test in the absense of evaporation.

i am just saying that my pool has never gotten that hot in the past. i would always take my cover off first thing in the mornings. the hottest my water has ever gotten was 92 and that was the end of July last year during the hottest part of the summer.

I am just splitting hairs. Leaving the cover on got your pool hotter. That is true. Was if because it somehow captured more heat from the sun? Or because it reduced the heat lost to evaporation? Likely it does not matter as much as the end result, but I contend it was the 2nd

If you could have stopped the evaporation without the cover (like perhaps with a liquid solar cover if there was 0 wind), perhaps the pool would have heated up just as much as it did with your physical cover on
