I've been noticing something this year. When I have the ph down closer to the target of 7.5 the water dries my skin more. If I let ph slowly rise to 7.8 ish the water has a better feel both in and out of the water once the skin dries. I have a virtually constant FC level that I micro treat every day, but I do the acid balance 2x a week.
Is this normal? It's a very slight observation. Also, this is the first year I've done borates. I didn't notice this effect prior to adding borates.
