Limestone coping is wearing away into pool

[poolbel]

I have a chlorine pool, with Limestone leuder coping. I have treated the limestone with a sealant but I'm constantly finding "crumbs" and chips in the pool. Some are fine and some are cratered with constant chipping off the top flat surface.

Anyone else experience this? Any way to stop the etching?

Thanks.

Nope, you got low quality stone.

Show us pictures of the problems.

You can see the difference between a cratered and normal one. And the chips in the pool.

Looks like cheap, low quality stone.
