Accu-Tab Blue SI 3⅛-Inch Calcium Hypochlorite Tablets

Accu-Tab Blue SI tablets are premium-grade calcium hypochlorite chlorine tablets specifically formulated for commercial aquatic chlorination systems. The 3⅛-inch diameter tablets feature a proprietary scale inhibitor (SI) to reduce buildup inside feeders and ensure long-term, consistent performance. Independently tested and certified by NSF International, these tablets are engineered exclusively for use in Accu-Tab systems, achieving predictable erosion and chlorine delivery rates.

Their distinctive blue-speckled appearance helps avoid use of incompatible white tablets such as trichlor or other non-compatible forms—maintaining both equipment integrity and compliance with local health regulations. Accu-Tab Blue SI tablets are recognized for being more pH-friendly than trichlor tablets or bleach, easing water balance management and reducing the need for pH adjustments.
