Like all indoor pool owners I want my pool to be in the best possible condition, both physically and visually. I've never had a better product for problem stains than cobalt cure and am very happy to have found a reliable source. I'm especially appreciative of your super fast delivery. Ordered on a Tuesday, delivered a couple of thousand miles away on Saturday. Many thanks!
