Thank you all for helping to arrive at the source of the sand. I should have thought of that earlier but it makes complete sense now. I'm glad it's nothing serious like plumbing or plaster. Almost had heart attack James about my finish LOL! Must maintain proper calcium in the pool.
James, one last question re: plaster. You ever hear of Jack's Magic The Blue Stuff for when you're first breaking in finish? I don't think my installers ever did add that but didn't know if it was a bunch of BS or if you think it's worth adding now? Probably marketing gimic?
