Haviland DuraChlor 3" Chlorine Tablets 25 lb Trichlor C008025-BX25L

The Haviland DuraChlor 3" Wrapped Chlorine Tablets (25 lb) deliver slow-dissolving, stabilized trichlor sanitation that keeps your swimming pool crystal-clear all season long. Each individually wrapped, 8-ounce tablet contains 90% available chlorine and is pressed without gummy binders on high-pressure equipment, ensuring clean, consistent dissolution without clogging feeders or skimmers.

🚩 PRO TIP

Place tablets in an automatic chlorinator or floating feeder and adjust the feed rate to maintain 1–3 ppm of free chlorine. Test water chemistry at least twice per week and superchlorinate weekly to 5–6 ppm for best results. Never mix with other chemicals in the same feeder.

FREQUENTLY ASKED QUESTIONS

How many 3-inch chlorine tablets do I need for a 10,000-gallon pool?

Under normal conditions, 1 to 2 ounces (roughly 1/8 to 1/4 of a tablet) per 10,000 gallons per day maintains 1–3 ppm. Adjust based on frequent water tests.

Can I put these tablets directly in my skimmer?

Yes — DuraChlor 3-inch tablets work in skimmer baskets, automatic chlorinators, and floating feeders. Never mix with other chemicals in the same feeder at the same time.

Are these tablets stabilized with cyanuric acid?

Yes. The active ingredient Trichloro-s-triazinetrione (trichlor) is inherently stabilized, protecting chlorine from UV degradation — ideal for outdoor pools.

What is the available chlorine content?

Each tablet contains 90% available chlorine (99% Trichloro-s-triazinetrione, 1% other ingredients).

Will these tablets clog my automatic chlorinator?

No. Pressed without gummy binders on high-pressure equipment, they dissolve cleanly and can even help clean gummed-up feeders.
