i recently decided to replace my hot tub cover, and in so doing, came across the idea of using a termal blanket (closed cell polyethelene foam, supposedly clorine resistent - but after receiving it I have to wonder if one needs to pay the premium for this from a spa store ??)
My goal was to protect the new spa cover's underside from chlorine vapor and to retain the water's heat better
I have noticed after a few days that my pH DROPPED from 7.9 to 7.4 and has remained constant. At first I thought it may have been beacuse of a chemical reaction between the spa water and the foam. But now I am wondering if the termal blanket has an effect on the outgassing caused by the spa's jets which come on (with some air bubbles) during the filtering/heating cycles. The blanket seems to trap below it all the gasses and vapor
Before the thermal blanket. I had to add muriatic acid every 3 or 4 days to lower pH even though I do not ever use the heavy duty jets, just those low pressure jets that circulate/hest the water for 2 hours , 3 times/day
TA is 50, and borates 40-50
So my question is: might the thermal blanket be a very effective tool to moderate , reduce, or eliminate pH rise due to the natural aeration of spa water? If so, this is for me a BIG advantage
