This is our 2nd year with a 15 x 30 AGP. We're strictly BBBrs.
This year our PH is higher than last (I actually had to add Borax regularly to keep it up last year). It is very steady--around 7.6-7.8, depending on which eye I use to look at the results, time of day, and wind direction 8). My problem is my skin feels very dried out after a swim. (1) Is it true this can be a side effect of high PH?
I got some Muriatic Acid Tuesday and added 2 cups which took it to 7.4, and left town for a few days. I did not test for ALK. I wondered if I had overdone it until I tested today and it's back to it's 7.7!
A large difference between last year and this is a large construction project 150 yards away that's imported massive amounts of fill dirt from what smells like a feed lot (PU) . I am constantly vacuuming silt (mixed with who knows what) off the bottom of the pool, very unlike last year. (2) Am I getting "natural" Borax from the construction project? We live in Colorado and I believe our soil is Alkaline, maybe 8.5?
Finally, (3) what can I do to make the water feel less drying to my skin?
Our numbers are:
FC - 4.5
CC - 0
CYA 25-27ish (thought I'd play with this low this year...now I'm following the high CYA thread and may adjust)
PH - 7.7
ALK - 110
CAL - 60
