Are you talking about your pump or a fountain?

(unless we are in the pool during the day) and my temps have been 87-88 in the mornings as oppposed to prior 91-92 deg.
Thats what i did, pump runs from 8 at night to noon. we also added the pvc sprinklers to the returns. it works awesome. the water fall wall we have doesnt cool it like those. we were 92-94 and now it stays 88-90, last night got down to 85

both.
I have a 24" sheer descent and 2 spouts in a water feature. (not a fine spray or mist like those are talking about with the DIY sprayers, etc). but it still must be doing something.
so my pool pump on overnight circulating the water and the water feature on as well

Thanks. I have always had my pump running, but I will start running my features at night too and see how it goes.

Its been enough of a difference to notice when using the pool for sure.
Heavy rain downpour yesterday eve and overnight and this am pool water temp was 86.
Ill take it.
This sounds similar to my results. Triangle shade + 1 return sprayer. My pool hasn't cracked 90F so far. My buddy at work who lives within a mile and similar pool without cooling measures said his water has been 94F all summer.

So run the pump at night and not during the day?

that's what I've been doing (unless we are in the pool during the day of course)
theory is to run it when the air temp is below the water temp. wont be drastic, but anything helps

If you have a salt water pool, running at night is better for chlorine generation since you are not fighting the sun's UV rays that zap your chlorine.

I used to tell anyone in designed pools for that the heater/cooler is worth the initial investment if you use your pool enough

I just order a rectangular sail shade that should cover 1/2 the pool. I’ll need to install two post on one side of my pool. How much tension do these require? I’m hoping I can attach taller metal post to my wood fence post for this.

I also installed a large triangle sunshade that covers up to 1/4 of the pool in the absolute heat of the day.
Came here to post this. Get the big triangle sun shade (quality one that won't rot), install some screw eyes (can paint if you have to put on a structure), and 3 carabiners and hook that thing up in the Summer strategically to block sun during hottest parts of the day. If there isn't anything to hook the triangle to around the pool, get a huge cantilever offset umbrella.
We did this at our old house (triangle) and it made a noticeable difference in the pool temp. 3-4 degrees.

You want a lot of tension. Slack makes it a sail in the wind that whips around a good bit. We used small ratchet straps and carabiners and it worked great.

We have a 30k glacier chiller that I panic bought at the end of pool construction. Days after we filled in early May the water was already near 90 degrees. We already had a gas heater purchased and installed so a combo wasn’t really an option. So far very pleased with the chiller. Not exactly sure about electricity costs bc when it’s time to chill the pool then it’s usually time to aerate the pond in our yard and run the AC what seems like 24 hours a day. The unit ran about 2800 last year plus 400 install. Which not exactly pleased with the way it was plumbed. Rest of pool is fully auto but this couldn’t be worked in. Also something is screwy and pool doesn’t circulate as well when it’s running. So bugs etc can accumulate. I run robot to compensate. It’s very effective temp wise though. We have NO SHADE until 5-6 pm. Water temps earlier this week when it was off were 94. Ran chiller from evening until am and woke up to 84 ish. It’ll pop up to 86/87 max during the day while running.

I got bored one day and did the math to figure out how much ice you'd have to add to the pool to reduce the temperature and it turned out to be an insane amount of ice.
As a teenager, we bought 300lbs of ice to toss in a 7-lane, 25y pool.
Didn’t budge from 88F.
Adult me laughs after learning several chemistry/physics concepts. But we had a pretty fun time back then.

With overnight air temperature dropping to 73°, my pool temperature was 82° this morning running those two aerators overnight at 2800 RPMs

One thing that helps mine is to turn off the auto fill. Let the evaporation take a bit out of the pool and fill it up with a hose prior to weekend swimming.

I have about same size pool, what chiller did you go with?
Posted on 7/28/23 at 10:32 am to Tigerbait1233
I've got two fountains on mine and run my pump at night and my pool water is still right at 90. It feels good though with the weather we currently have. Without the fountains, I bet it would be about 95. My pool gets full sun from 7 a.m. until 7 p.m.

Return Jet fountain sprayer/aerater thing.
Should be good for around 5-8 degree difference in my experience, which isn’t bad.
