I know this is an old thread.
I got an aerator that sprays a rainfall pattern of drops about 8 feet into the air. I was trying to measure if it actually did anything. The pool did seem maybe three degrees cooler but it’s hard to control for ambient weather conditions (cloud cover, humidity, wind).
I decided to run a poor man’s test and put a cup under the bottom of the rainfall pattern (just before it falls back into the pool) to collect some water and tested the temp relative to the pool water temp with a high end kitchen thermometer.
There was about a 2 degree difference (91 deg water to 89 deg water). This was during the peak of the day at the lowest relative humidity (around 40%) and around 98 degree air temp.
I was hoping for a much larger temperature drop. I would think that given the flow rate through the aerator (I would guess around 10 gpm), vs my pool volume (20k gal), that mixing in 10 gpm of 2 degree color water into a 20kgal pool would not do much. Running 24 hours per day wouldn’t even turn over the pool volume once, and that doesn’t account for the loss of effect due to mixing, or with a likely lower delta-T at night when the relative humidity is near 100%.
I still run it for a day before I expect to swim, but not sure if I’m just running it for a placebo effect, haha.
