Maintain a Clear Pool

Your pool chemistry can change quickly. Test your pool water weekly to ensure your Free Chlorine level remains between 1 – 4 ppm.  Apply a preventative algaecide weekly to fight algae and keep your pool clear.

Maintain a regular cleaning regimen. Skim water surface, brush walls, vacuum and empty skimmer baskets at least once per week. Download the Clorox® Pool app on the Apple App Store or Google Play for expert water analysis and product and dosage recommendations.

This season, spend less time maintaining and more time enjoying your swimming pool!

Don’t waste you money on this item !

I wouldn’t recommend this problem . You can use the complete gallon and still have problem with algae . I changed over to BIOGARD products , yes it cost more but you use less and get 100% better results . Also BIOGARD products diensnt break down ypu pool liner as well it’s better to swim in . Enjoy !

Terrible Product

I followed all directions. I backwashed and rinsed the pool before adding. I used 5 gallons for my 50,000 gallon pool. I added it at night and kept the filter running continuously. I made sure the ph was correct. I made sure the chlorine levels were correct. My pool is still totally yellow. Not one bit clearer than before I spent $75 worth of this product. Do not recommend. It does not work.

Better than the rest

I’ve had a pool for 20 years. Every year I have trouble with algae. Until I found Clorox brand Fungicide I bought every brand I could find and had no results, fighting algae through July to September. Not so with Clorox brand. I use it weekly and I never have trouble with algae anymore.
