Due to a long drawn out illness that resulted in the loss of my mother in law, I wasn't able to give my IG vinyl liner pool all the loving care it deserved this summer. I now have what I'm pretty certain is calcium scaling on the liner, it feels very rough and actually skinned a couple of my toes, like sandpaper would. PH has been higher than I like for the majority of the season, and our fill water is high alkalinity (and hard), but it couldn't be helped, I was needed elsewhere.
I just had a thought. Low end of PH for vinyl liner is 7.0. I'll be closing the pool soon. What if I lower the PH to 7.0 right before I close and hold it there all winter? That would be about 6 months for the lower PH to work on the scale.
Crazy? Worth a shot? What would you do?
