What Customers Are Saying

Customers overwhelmingly praise this pool shock for transforming cloudy or green water into crystal-clear blue within hours, with many seeing results in as little as 15 minutes. The 6-in-1 formula effectively combats algae including black algae, and dissolves quickly without premixing. Most users report consistent performance across pool types and use it weekly for year-round maintenance. Reviewers call it the best shock they've used, appreciating its reliability and ease of use. A few mention concerns about price and occasional packaging discrepancies, but these do not diminish overall satisfaction.

Learned My Lesson

Would Not Recommend

Better to use Liquid Chlorine instead of these if you use tabs that raise CYA over time. My CYA got out of hand and made a mess of our pool. Won't take that chance again.
