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.

Great Product

Best product I have used in 20 years as home owner with a 20,000 gallon pool in Arizona. You must clean your filter, vacuum your pool, brush your pool, and balance your chemicals. This Clorox product will take your pool to the next level. Bought the 24 pack at Costco. Highly recommended.

This product is terrible! So my pool had been perfect! Crystal clear, perfect balance for a month since opening. I bought this as I ran out and needed shock after a fun family weekend. Bought this at my local Lowes and put a bag in that afternoon. The next morning my wife asked what I did to the pool. I looked outside and it had started to turn what looked like green! I thought, well, maybe this new “Blue” put a blue cast to the water. Checked the chlorine level and it was still a little weak. Added another bag and it is now filled with a green cloud! What the heck! My perfect pool is now terrible! I have 4 bags left. Trash now as I ordered the good stuff again from Doheny’s! Never again. Clorox! Ugh!!!!! You need to make it right!
