  • 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.
  • 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.
  • TRUSTED POOL SUPPLIES - Rx Clear is the best choice for swimming pool accessories and pool chemicals and supplies.

Rx Clear Super Shock for Swimming Pools | Chlorinator and Algaecide | 68% Calcium Hypochlorite | Kill Pool Algae for a Crystal Clear Pool | Bucket - 24 Lbs

$159.94  in stock
as of April 20, 2022 4:31 pm

Features

  • POOL SHOCK TREATMENT - Rx Clear’s Super Shock contains 68% calcium hypochlorite, yielding 65% available chlorine making this similar to Mega Shock, but slightly less concentrated. This shock will raise your free chlorine levels, water hardness, and pH levels giving you crystal clear water for a more enjoyable swimming experience. Due to its high percentage of chlorine, Super Shock is very effective and efficient for a quick chlorine boost.
  • MIX BEFORE YOU FIX - It is best to dilute Super Shock in a bucket of water before dispensing it around the pool which can prevent liner staining and cloudy water. Add this powder to a bucket of water before you add it to your pool. Add a 1 lbs bag per 10,000 gallons of pool water.
  • POOL SHOCK WITH ALGAECIDE - Kill the algae in your swimming pool by adding 3 bags of shock per 10,000 gallons of pool water. Rx Clear strives to provide quality products for a safer, cleaner, and more enjoyable swimming experience. When it comes to correcting your swimming pool, Rx Clear does it all giving you crystal clear water that fits your needs.
  • WORKS BEST AT NIGHT - For the best results use Super Shock at night in order to prevent the sun from eating up the shock since it is not stabilized; it’s best to shock when the sun isn’t out for maximum performance. Do not swim for 8 to 10 hours after application.
  • POOL CHLORINE SHOCK - Maintain your swimming pool or spa with reliable pool chemicals and treatment supplies that you can depend on from Rx Clear. The Rx Clear brand is the premier choice for a trusted cleaning product to keep your pool in its best shape.
