More Details
Main highlights
- 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.
- 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. 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.
- 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.
- CLEAR WATER FOR SAFE SWIMMING - Swimming in crystal clear water does not mean your skin has to suffer. The granular chlorine is 99% sodium diclor making a relaxing swim not as harsh.
