The Mainstays Small Pool and Spa Maintenance Kit - 4 Accessories is a complete starter kit for any owner. The 4 accessories are: one floating chemical dispenser, one water line hand brush, one leaf skimmer, and one small telescopic pole. The chemical dispenser can accept chlorine or bromine so it can be used either in the pool or spa. The water line brush is a necessary item as it cleans off all the unwanted body oils, scum, and debris that can get stuck on the walls. The leaf skimmer is small in design since most pool styles are big and will scratch the hot tub or small pool. The telescopic pole attaches to the leaf skimmer and will extend up to 4' which allows you to work around your small pool or spa.
