I have a gunite pool with a SWG and I'm using borates but I still have a slight scale problem. I'm constantly lowering the pH and brushing/scraping to remove the scale. Most of it is very small and turns into "dust" as I brush it, but some is larger and comes off in "chunks" (especially on the tile above the water line).
Anyhow, I was wondering what happens to the scale that is removed? Does it stay in the water and reform as scale? Does it get trapped the filter (DE in my case) and get removed when backwashing? After I brush it off, does it remain to cause more damage?
