First let me say thank you for helping me get my pool clean and swim-able again last week! I wish I'd found this site years ago - I would've saved so much money and pool downtime. And let me properly introduce myself.... I'm Stacey, living in Northern Virginia,
with my husband and 4 children ages 16-23.
Now that my numbers are in order (see below), I want to address this weird white film on the pool walls that gets on swimmers if they touch it. Last night we had a pool full of swimmers commenting on it and the resulting "pokey" feeling it leaves on the skin. It only happens when a swimmer touches the pool wall and only on the skin that touches the wall. The film is easily rubbed off but will stay on the skin after getting out of the water if not rubbed off. The resulting "sensitive" rash lasts for about 12 hours, especially irritated when touched or rubbed. We had this same problem last year.
The pool was originally built probably 30 years ago. We have been in this house for 15 years. We had the pool walls painted white 5 years ago. There is peeling and pocking and the pool needs a re-do, but please not this season. BTW while the pool is blue, it remains cloudy in the deep end.
My questions are
Can the white film be addressed as a chemistry balancing problem?
If it is the plaster/paint can it be managed until the end of swim season, end of September?
How can this problem be avoided in the future?
Is it safe to swim?
