Sooooo. We just an IG pool installed. PB came over yesterday to review the final things with us. We purchased a safety cover, but he told us he did not feel comfortable installing it this year. He said he had a similar situation last year (new build and covered shortly after) and the area where the cover covered the concrete left a line due to the concrete not curing fully. So he said he's going to tarp it with water bags for this winter. We have kids...and dogs. Anything I should be concerned about with going this route for one winter?
