Quick Product Summary

GLB Super Charge 68% Cal Hypo Pool Shock 71428A is a 1 lb granular calcium hypochlorite treatment formulated for swimming pool superchlorination. With 68% calcium hypochlorite and 65% minimum available chlorine, it helps reduce organic waste, control algae, and support proper chlorine sanitation. The label-directed shock-treatment rate is 1 lb per 10,000 gallons of swimming pool water. Pool owners should test and balance their water, confirm pool volume, and always follow the current product label before treatment.

Best For

• Routine swimming pool shock treatment
• Superchlorination after increased pool use
• Reducing organic contaminant buildup
• Supporting chlorine sanitation
• Pool owners who want a calcium hypochlorite granular shock
• Treating approximately 10,000 gallons with one 1 lb package when used at the label rate

Why This Matters

• Organic waste can increase chlorine demand and make sanitation more difficult
• Superchlorination helps restore an effective chlorine residual after contaminants accumulate
• Calcium hypochlorite provides chlorine without relying on a stabilized chlorine tablet
• Correct dosing starts with knowing the actual pool volume
• Testing the water before and after treatment helps prevent improper chlorine levels
• Proper chemical handling is essential because calcium hypochlorite is a strong oxidizing pool chemical

Common Signs You Need This / Use This When

• Your pool is due for its normal shock treatment
• Heavy swimming has increased the contaminant load
• Organic contaminants have accumulated in the water
• Algae control requires a label-directed shock treatment
• Chlorine demand has increased and water conditions indicate superchlorination is appropriate
• You need a 1 lb calcium hypochlorite shock identified by GLB SKU 71428A

Product Specifications

Compatibility / Fitment Notes

GLB Super Charge is a swimming pool chemical rather than an equipment replacement part, so correct selection depends on the pool volume, current water chemistry, sanitation program, and product label rather than equipment model fitment.

Before treatment, accurately determine pool volume and test the water with an appropriate pool-water test method. Never assume that one full bag is the correct amount for every swimming pool simply because the package contains 1 lb.

Calcium hypochlorite chemistry should also be considered as part of the pool's overall water-balance program. Follow the current GLB label and adjust pool chemistry only with products intended for that specific purpose.

Installation / Use Notes

Read the entire product label and precautionary statements before use. For the label-directed shock treatment, GLB Super Charge is applied at 1 lb per 10,000 gallons of swimming pool water and scattered over the pool-water surface while the pool is not in use.

Never mix GLB Super Charge with another pool chemical, and do not place it in a feeder, floater, or skimmer. Add the product only as directed by the current label and test the chlorine level before swimmers re-enter the pool. Keep the product dry and stored according to label instructions.
