Swimline 21 Ft Round Above Ground Pool Cover w/ Chemical Kit (No Pool Included)

The Swimline 21 Foot Round Above Ground Winter Swimming Pool Cover is great for keeping your pool in good condition during the cold, winter months, but it will also make getting your pool back into shape in the spring much easier.

This pool cover is made of laminated polyethylene sheeting woven with thick, high density polyethylene stitching, which ensures superior tensile strength and durability. It has also been treated to provide maximum resistance to damaging ultraviolet rays.

This package also includes a winterizing chemical kit.

Prepare your pool this winter with our pre-measured winterizing closing kit. Our powerful combination of winterizing chemicals help to prevent algae growth, eliminate minerals and metals that can cause liner stains and build-up, and purge lotions, oils, grease, and grime from your pool water. Ordering a larger winterizing kit than your pool size may help to protect against winter cover problems.

- Winterizing kit includes:

- Winter treatment - 1 quart

- Stain control - 1 quart

- Non-chlorine shock - 1 pound

- Small winter floater (1)

This kit can be used on salt water pools!
