Algaecide, Rx Clear Stabilized Granular Chlorine | One 50-Pound Bucket | Use As Bactericide, and Disinfectant in Swimming Pools and Spas | Fast Dissolving and UV Protected

#ad
Rx Clear #ad - The granular chlorine is 99% sodium diclor making a relaxing swim not as harsh. Fewer chemicals needed - our dichlor is ph neutral, meaning less chemical adjustments to be made by you! This pool chlorinator acts as a sanitizer, pool algaecide, and disinfectant.

Dissolves quickly - add 1 oz of this cleaning chemical to your pool for every 5, 000 gallons your pool contains, daily for the best quick water treatment maintenance. This granular chlorine dissolves in a 4-foot column, so there is no need to worry about bleach damage on your pool liner as with chlorine tablets. Clear water for safe swimming - swimming in crystal clear water does not mean your skin has to suffer.

Trusted pool supplies - Rx Clear is the best choice for swimming pool accessories and pool chemicals and supplies. Long lasting - dichlor resists uv light, lasting longer than other types of chlorinating supplies due to built in stabilizer for your swimming pool, hot tub, or spa.
