Keep pool water inviting and swimmer-friendly with the HTH 52036R Pool Care Shock Advanced. This fast-dissolving, 4‑in‑1 treatment works quickly to curb bacteria and algae, reduce chlorine odor, and restore a pristine, crystal-clear appearance your pool deserves. Designed for weekly use, it helps you manage common water challenges with ease, so you can enjoy the pool without distraction.

Key benefits

  • Fast-dissolving 4‑in‑1 formula that kills bacteria and algae, reduces chlorine odor and eye irritation, and quickly restores crystal clarity.
  • Cal Hypo–based formula sanitizes without adding cyanuric acid (CYA), helping to prevent overstabilization or chlorine lock.
  • Compatible with all pool types, including vinyl-lined and saltwater systems, for versatile use.

Why choose HTH Shock Advanced

  • Weekly shock treatment designed to address many common water issues within about 24 hours in many cases.
  • Pairs well with HTH 6‑Way Test Strips to test and balance your pool water twice weekly for best results.

Usage is simple: dissolve the product and distribute it evenly over the pool surface while the pump runs to circulate the water. For ongoing clarity, test and balance your water twice weekly with the HTH 6‑Way Test Strips and adjust as needed. With regular use, you can maintain a pool that looks inviting and feels comfortable to swimmers, even after busy days or weekend gatherings.

Note: This Cal Hypo shock is designed to support clear, balanced water across many pool configurations, including those with saltwater systems or vinyl linings. As with any pool care routine, follow label directions and test regularly to tailor treatment to your water needs.
