Swim-Ready in 15 Minutes

Fast dissolving formula works quickly so you can treat and swim in just 15 minutes.

Maintain a Clear Pool

Crystal clear water starts with pool shock. Shocking your pool water helps to remove contaminants that may cause cloudy water and algae. Apply a pool shock treatment weekly as part of a regular maintenance routine.

Maintain a regular cleaning regimen. Skim water surface, brush walls, vacuum and empty skimmer baskets at least once per week.

Test and balance your pool water weekly. Your test results will tell you if your water parameters are unbalanced. If needed, apply the appropriate products to restore balance. Download the Clorox® Pool app on Apple App Store or Google Play for expert water analysis and product and dosage recommendations.

Good stuff/ Getting to pricey

Been using for years, going to start looking for alternatives due to prices. 2 years ago I paid $48 for 12 lbs at Walmart yesterday pd $65 big increase. Getting to be a rip!

No support

I bought a 1Lb jar but then found out there is no real breakdown for using in a spa. Using the web page and indicating my spa was only 500 gallons, it showed to use .04 Lbs . Not sure how to measure .04 lbs so I emailed Clorox and requested they break that down to tsp or tbs. No reply. I guess I’ll have to go to the spa store and buy a product I can rely on.
