When to Use the Kit

Use the In The Swim Basic Pool Opening Kit when opening your pool for the swimming season, typically in spring (March through May depending on your location). The kit is designed for pools that have been properly winterized and covered, providing the chemicals needed to restore water quality and prepare for summer use.

What's Included in the Kit

Shock Treatment

The kit includes calcium hypochlorite shock (typically 1 to 2 lbs) to kill bacteria, destroy organic contaminants, and oxidize pool water. Shocking is the critical first step in restoring water quality after winter.

Algaecide

A preventative algaecide (typically polyquat based) helps prevent algae growth during the opening process and throughout the early season. This non-metallic formula won't stain pool surfaces.

Clarifier

Pool clarifier helps filter capture small particles, improving water clarity by binding microscopic debris together so your filter can remove them more effectively.

Stain and Scale Preventer

Metal sequestrant prevents staining from metals in the water and helps control scale formation on pool surfaces and equipment during the opening process.

Pre-Opening Preparation
