Frequently Asked Questions

AI
Pucks are slow-dissolving tablets ideal for maintaining steady chlorine levels in skimmers or floaters. Granules dissolve quickly and are used for shocking the pool to raise chlorine levels rapidly or for spas where fast action is needed.
Yes, if your pool is exposed to direct sunlight. Stabilized chlorine contains cyanuric acid, which protects the chlorine from UV degradation. Uns stabilized chlorine dissipates too quickly in sunny outdoor pools to be effective.
Shock your pool weekly during heavy use or after heavy rain. If the water appears cloudy or has a strong chlorine odor, shock immediately. Regular shocking prevents algae buildup and keeps water clear.
