Our granular chlorine the strongest on the market. Don't be misled by a lower price on a lower percent of active ingredient; you are paying for a strong bacterial killer, so make sure you get it!

Quick-dissolving chlorine also means no messy residue in your pool!

UV rays from the sun can burn off chlorine in your pool. Our granular chlorine has an added UV inhibitor, which slows down this process significantly, keeping your pool sanitized for longer.

Because of its quick-dissolving and powerful formula, Leslie's Chlor Brite is perfect for everyday use, as well as weekly shocking, or superchlorinating your pool.

Both effective and powerful, Leslie's Chlor Brite features 99% sodium dichloro-s-triazinetrione, also known as dichlor - the highest amount you can buy! Chlor Brite is designed for easy use. Leslie's Chlor Brite dissolves rapidly, which means it won't sit on the bottom and bleach your pool, and it won't leave any residue on pool walls.

Leslie's Chlor Brite provides constant and effective chlorination, ease of handling, and an indefinite shelf life. Dichlor granular chlorine is perfect for above-ground, vinyl-lined, fiberglass, and painted pools. Because it dissolves rapidly, it will not harm the walls of the pool. The pH level of Leslie's Chlor Brite is between 6.5 and 7.0, which is almost neutral. This makes it very easy to regulate your pool's chemical levels. Dichlor also features a built-in stabilizer, so the sun's harmful UV rays will not disrupt the chlorination process.
