HASA Liquid Chlorine Pool Shock

Because it is already in a liquid state, HASA provides immediate sanitization without the risk of bleaching pool surfaces that can occur if granules settle on the bottom.

Yes, this formula is compatible with all pool surfaces, including vinyl, plaster, gunite, and fiberglass. However, you should always dilute the chlorine according to your pool's volume and ensure proper circulation to prevent localized staining or damage.
