Name: Cindy    City: Chapel Hill

Question: Last summer we had stain to appear and finally cured that problem by lowering the pool then filling it back up. Limer was left with permanent stain in several places. This summer with this heat wave well underway in Tennessee, the stains are appearing again. Looks like dirt on the bottom, seams, and sides but will not brush or vaccuum away. Anyone out there have any cure for the problem?
