Cooling a Hot Pool

Actually, aerating will lower your pH, but yes, it will have some effect on your water - however, raising your pH is easier than lowering it - simply add borax.

Aerating will raise pH but without raising alkalinity (much). So the end result, after adding acid to lower your pH again, will be lower alkalinity.

Matt and Kurt,

I have been pleasantly surprised at how little water is lost to evaporation. Over the 3-day period I just completed, I lost little more than 3/4". In this heat, I would expect 1/4" daily anyway, so it appears the extra evaporation is pretty minimal.

Secondly, I can't give really valid data on pH because my stupid pool wants to raise pH all on it's own. It has done this for the five years I've had it.....don't know why. I typically add acid about weekly and I supect I've had to add a little more because of the aeration (I keep sloppy data) but it's not anywhere near double....probably more like 25%. I need to check Alk but haven't done so yet.

Lastly, I agree with Kurt that it should be pretty inneffective in high RH. When the temps get in the upper 90's, it's pretty hard to get RH much above 50% in midday here so that's primarily when I run it.

All in all, I would rate it right up there with Ben's kit as the best money I ever spent on my pool.

oops - sorry ! Don't know what I was thinking there except that maybe I was in need of another coffee!
A fountain is something I can't do simply because I can't afford 1/4" a day, heck - I can't afford 1mm a day!
My solar blanket is on unless we swim, if the pool gets too hot I just change my timer to run at night and keep the solar panels on - tend to be able to drop 5 degrees that way

Happens to us all.
