Hello! We just moved into this repo house back in July. I changed the pump and filter sand before we even moved in and got the pool all cleaned up. It stays pretty clean except some minor growth on the shaded wall every so often which brushes right off and takes a while to come back, yes usually if I let the chlorine dump like over the winter with the cover on... Anyway, as I cleaned it up the plaster showed more and more of its inconsistent coloring... blotchyness really. I don't know if that means it needs to be replastered or what. I had attempted to broom sections with a firm (metal wire?) pool brush and it would have a cloud. I stopped in fear it was just tearing up the plaster but now I wonder if it is the plaster being garbage or something else.
Here is what it looks like in a wide angle in the deep end:
And here it is zoomed in on some
Yesterday I drained out some of the pool so I could see the plaster. I guess it's not white... but you can see where I took a scraper real quick and scraped off the color, not sure what that means... The stuff that scrapes off is kind of a light teal color.. didn't show well in the picture.
Thanks for any insight you can give!
