Frequently Asked Questions

  • What are individually wrapped chlorine tabs, and why are they beneficial?

    HTH™ 3" Chlorine Tabs ADVANCED Wrapped use the same multi-action formula as standard HTH™ 3" Chlorine Tabs ADVANCED, but each tab comes in its own sealed wrap. This helps reduce chlorine dust, lessen chlorine odor in the pail, and limit direct skin contact during handling.

  • Do I remove the wrapper before adding wrapped chlorine tablets to my pool?

    Yes. Remove the wrapper before adding the chlorine tablet to your floater, automatic feeder, or skimmer basket.

  • How do I use HTH™ 3" Chlorine Tabs ADVANCED Wrapped in my pool?

    Unwrap the tab and add it to a chlorine floater, automatic feeder, or skimmer basket. Use 1 tab per 10,000 gallons per week as a starting point, then adjust as needed to maintain free chlorine between 1–4 ppm.

  • How long do individually wrapped chlorine tabs last?

    The wrapped and unwrapped versions of HTH™ 3" Chlorine Tabs ADVANCED contain the same formula and typically dissolve over 5–7 days under normal pool conditions. Test the chlorine level every 3–4 days and replace the tabs as needed.

  • Why are individually wrapped chlorine tabs better for storage and handling?

    Individual wrapping minimizes direct chlorine exposure during handling, reducing chlorine dust and skin contact while helping lessen chlorine odor in the pail. Each sealed wrap also protects the tab from humidity, which can cause unwrapped tabs to break down over time.

  • Are HTH™ 3" Chlorine Tabs ADVANCED Wrapped the same formula as the unwrapped tabs?

    Yes. HTH™ 3" Chlorine Tabs ADVANCED Wrapped contain the same multi-action formula as standard HTH™ 3" Chlorine Tabs ADVANCED—trichlor sanitizer, built-in clarifier, and algaecide. The only difference is the individually wrapped packaging for easier, cleaner handling. Performance and dosing are the same.
