Our 3-inch chlorine tablets are the most common and versatile size for residential pools. They fit standard automatic chlorinators, floating dispensers, and skimmer baskets. If you have a typical in-ground or above-ground pool, 3-inch tablets are the right choice. For very small spas or specialty systems, check your equipment manual before ordering.

Place 1–2 tablets per 10,000 gallons of pool water in your automatic chlorinator, floating dispenser, or skimmer basket. Do not throw tablets directly into the pool, as they can bleach liners or damage surfaces. Adjust the number of tablets based on pool usage, temperature, and chlorine demand. Always maintain a free chlorine level of 1–3 ppm.

Store the bucket in a cool, dry, well-ventilated area, away from direct sunlight and moisture. Keep the lid tightly closed when not in use. Do not store near acids, ammonia, or flammable materials. Never mix chlorine tablets with other pool chemicals, especially shock, in a confined space.
