Product Description

A three-part system that eliminates contaminants with Oxy-Brite® shock oxidizer, prevents algae growth with Algimycin® Winter algaecide, and provides mineral protection from scaling and staining during the winter months with Sequa-Sol® sequestering agent.

Algimycin® Winter algaecide is an EPA registered, non-foaming, non-metallic winter algaecide that keeps pools algae-free all winter.

Oxy-Brite® chlorine-free shock treatment oxidizes organic contaminants that cause odors, cloudy water, skin and eye irritation. Oxy-Brite® shock oxidizer also contains unique blue crystals that brighten the water.

Sequa-Sol® sequestering agent holds iron, manganese, copper and calcium in solution so these minerals do not react with other elements in the water.


  • Contains everything you need to close your pool.
  • Makes spring pool opening hassle-free

If you live in a mild climate and your pool will remain full during the cooler months, you should check with your dealer to see if your filtration system should continue to operate. If so, you will need to add a sanitizer, an algaecide and a sequestering agent on a regular basis.

Ozone, chlorine and bromine sanitizers. Also great for salt water pools!


  • Algimycin® Winter Algaecide

The GLB® Pool Closing Kit has 3 components: a non-chlorine shock to rid your pool of contaminants, an algae preventative, and a sequestering agent to prevent staining and scaling.
