Pool Shock Treatments

Shock treatments are high-dose sanitizers that oxidize organic material, kill bacteria, and eliminate chloramines (the smelly byproducts of chlorine). Regular shocking is essential to keep water clean, clear, and safe.

Why It Matters

Over time, chlorine binds to contaminants, forming chloramines—which smell bad and reduce sanitation. Shocking breaks these bonds, resets your sanitizer, and improves water quality almost instantly.

When to Shock

  • Weekly as part of routine maintenance

  • After heavy pool use, rainstorms, or algae

  • If water looks dull, cloudy, or smells “off”

Types of Pool Shock

  • Calcium Hypochlorite (Cal Hypo) – Strong and fast-acting; adds calcium.

  • Dichlor Shock – Stabilized; good for regular use.

  • Non-Chlorine Shock (Potassium Monopersulfate) – Oxidizes without raising chlorine levels. Ideal for spas.

Tips for Using Shock

Shock at night to prevent sunlight from burning off active ingredients. Run your pump for several hours and don’t swim until sanitizer levels return to safe levels (under 3 ppm for chlorine).

Takeaways

  • Shock breaks down waste and restores chlorine power.

  • Use weekly or as needed after pool activity or algae.

  • Choose your shock type based on pool conditions.
