My pool was re-plastered 6 months ago - standard white plaster. I assume my issue may be a deficiency in the plastering process? I brushed it for 30 days but almost immediately noticed "dirt" or something sticking in some areas. Started SWCG somewhat after the 30 days. Now that I am in the pool, the "dirty" areas are rough, some like a file, some like sandpaper. Since this happened so fast I don't think it is scale. (I did find a little scale on waterline tile - mostly at the tanning ledge. I could rub it off with my finger, so I took a vegetable brush to clean it all up.)
Now I need to decide what to do about these rough areas. My biggest concern is these will be prime targets for algae. On the tanning ledge I used 60 grit wet/dry sandpaper which did a good job with some elbow grease. Seems pretty smooth, but I probably need a finer grit to discourage algae. How fine should I go?
The big challenge is the deeper parts of the pool that I can't reach (with my head above water).
After using one sheet of sandpaper, CH went from 450 to 475-500. If I need to drain the pool to adequately deal with this, what is the best way to polish the plaster so it is nice and smooth?
