Not that I have noticed - my ta is usually 60/70 though so my ph stays rock solid.
My humidity is 72% right now - I believe it’s closer to mid 60’s during the day & i am currently running it from 8:30 am to 8:30pm. We had a cooler spell for a minute so I took it off & just put it back on yesterday morning- my water is 87 degrees- it was 90. The evening temps have some to do with that too. But it does help over several days. My car said it was 103 degrees out today. Sometimes I will run it around the clock a couple days to help cool things down.

They sell the exact one for double that at my local pool place.
There are also ones with lights now

I made one out of pvc for my intex pool but never adapted it to this pool as it was inline with the plumbing & has 2” fittings on it.
I did have to add zip ties to this one to keep it from blowing the holy pipe off but to be fair the one I got was from amazon warehouse for a reduced price so it may have been missing a piece.
