Winterizing chemical pool kits are premeasured and packaged according to specific pool size, making the pool winterization process a straight-forward and easy-to-handle process for any pool owner. Such kits include a pool shock chemical, a time-release pool chemical floater, a stain elimination pool chemical, an algaecide, and a separate pool chemical specialized in removing oils and grease from the water. Winterizing chemical pool kits are effective in eliminating leftover carbon dioxide, which is one of the main food sources for pool liner-damaging algae.
