CLOROX Pool&Spa 23006CLXCA Xtra Blue Chlorinating Granules, 6-Pound

I've been using the stuff for years, does a great job of increasing chlorine levels in the pool without throwing off any other levels. Great stuff, i'll continue to use.

As a dedicated pool owner, I recognize that proper water chemistry management is a complex, continuous process that demands reliable, high-quality inputs. The CLOROX Pool&Spa All-in-One XtraBlue Chlorinating Granules do not simply sanitize; they provide a multifaceted solution that drastically streamlines weekly maintenance and delivers demonstrably superior water quality. The All-in-One designation is genuinely earned. This product incorporates a highly effective stabilized granular chlorine (Dichlor), which ensures the free chlorine residual is maintained despite UV degradation, alongside powerful algaecidal and sequestering agents. This prevents the growth of resistant green algae and helps bind up trace metals that can cause staining or clouding, significantly reducing the need for costly ancillary shock treatments. The granular formulation is a huge advantage over traditional tablets. It offers a rapid and complete dissolution rate, allowing for immediate application and adjustment of chlorine levels without the prolonged wait time or risk of corrosive damage associated with placing tabs directly in the skimmer. The "XtraBlue" visual indicator, while subtle, confirms dispersion and gives a satisfying, immediate feedback loop that the chemical load has been delivered and is active. For those who prioritize preventative care over reactive treatment, the 6-pound quantity is an economical staple. This product has simplified my pool routine while significantly improving clarity and microbial control. For high-performance pool sanitation and maintenance, this is now my standard operating input.

This is the best chlorine I found it's way better than your local liquid chlorine sitting out in the sun for who knows how long. Keep in mind too much of this product will cause acid problems Google the ingredients

Update: We still love this, but this shipment arrived with about a cup of product all over inside the shipping box. Need to revisit how the container is sealed! Dint need replacement- just better containment. Opening the box, I know I inhaled a bit. Yuck! I don't like having to measure, but works so much better than the tablets and the pkgs were out of stock.

Great shock treatment
