We have an in-ground pool with the following specifications
We swam in the pool 2 weeks ago and it was fine.
Between that time and now, the water has 'looked good' and I've been maintaining CL and pH.
** We stepped in last night however, and the "entire surface" of the finish has a sandpaper-like grit feel.... It's even on the Polaris and the cleaner hose.
In a small area of the wall I used a plastic putty knife and the grit comes loose. A pumice stone works really well, but we went through 3 stones just attempting to remove the grit from the 1st large step/sun deck. I tried the standard pool brush, both nylon and wire, but it does not remove the grit.
To Reiterate:
So, given the fact that it can be scraped off, my understanding is that its not calcium scale but perhaps calcium crystals? In my research however, it seems that this is more common in colder climates and especially present on pool openings. Given this, its especially confusing because my climate is 100+ degree days and the pool has been open for 3 months now with no issues.
I'd really would like some community feedback here.
I went to our local pool supply store, but I'm not entirely confident in them or their recommendation. They recommended, which I purchased, but have not yet used: Stain & Scale Remove which indicates 'Highly concentrated calcium and metal stain remover'.
Thanks again. Hope to hear some feedback soon.

To Reiterate:
- Plastic Putty Knife: works OK.
- Metal Putty Knife: works very well and removes the grit
- Pumice Stone: works very well, just eats up the stone quick
- Standard Nylon Pool brush: does not work
- Stainless Wire Pool Brush: does not work
