Jandy Stain Master

Pool plaster stains. Rust, copper, dirt, etc. None too pretty to look at, but is it worth draining the pool to do an acid wash? If your stains or scale are localized, you can deliver small amounts of acid or sequestering agent or even chlorine through the Stain Master directly to the source. Connected to your telescopic pole, the Stain Master siphons liquid through a hose and cap from a container placed on the pool deck.
