How long do chlorine tablets last?

Slow-dissolving chlorine tablets typically last 3-7 days depending on pool size, water temperature, and sunlight exposure. Warmer water and direct sunlight cause faster dissolution.

Can I use these tablets in my hot tub?

These are formulated for swimming pools, not hot tubs. Hot tubs require different chlorine products and sanitization methods due to higher water temperatures and different chemistry requirements.

How many tablets do I need?

For a typical 15,000-20,000 gallon pool, use 2-4 tablets per week. Larger pools may need more. Always start with recommended dosing and adjust based on chlorine level testing.
