• Cyanuric Acid (Stabilizer): 40-50 ppm (reduces UV degradation)

---

What's the Best Way to Clean Your Pool Before Winter?

A thoroughly cleaned pool uses sanitizer more efficiently and prevents staining during closure. Debris and algae left in the pool will consume chlorine and create problems when reopening in spring.

Complete cleaning process:

• Skim all leaves, insects, and floating debris from the surface
• Brush walls, steps, and hard-to-reach areas to dislodge algae
• Vacuum the pool floor thoroughly, including corners and deep end
• Clean out skimmer baskets and pump strainer basket
• Backwash or clean your filter system completely
• Remove and store pool accessories (ladders, toys, floats)
