Went on vacation for 3-4 days last week and used some tabs (first time in a long time). When I came back, I was cleaning out the skimmers and doing yard work etc. There was a leftover piece of tab about the size of a then 50 cent piece that I accidentally left on the side of the pool and me/my wife/the dogs knocked it into the pool. It was dark when we finished up so I didn't see it and this morning I noticed it in there. I fished it and it broke into a million pieces so I ended up just vacuuming it out.
However, it looks like it left some stains on my plaster from being left there over night. Is this permanent?
