How much pool shock do I need for my pool?

The amount depends on your pool size, current chlorine level, and water conditions. Use the Pool Shock Calculator on Standard Chemicals to determine the exact dose based on your pool.

Does calcium hypochlorite add cyanuric acid (CYA)?

No. Calcium hypochlorite does not add cyanuric acid, making it ideal for pools with high stabilizer levels where additional CYA would reduce chlorine effectiveness.

Why is my pool still green even when chlorine levels are high?

A pool can remain green due to algae growth, poor circulation, or high cyanuric acid levels reducing chlorine effectiveness. In these cases, a stronger shock treatment is typically required.

When should I use pool shock instead of chlorine tablets?

Pool shock is used for rapid chlorine increases to treat algae, cloudy water, and contamination, while chlorine tablets are used for slow, ongoing sanitation and maintenance.

Q: What is calcium hypochlorite pool shock?

Calcium hypochlorite (cal hypo) is a fast-acting, unstabilized chlorine used to quickly raise chlorine levels, kill algae, and restore water clarity without adding cyanuric acid (CYA).
