Stain Control & Cleaners

Stains may be unsightly but they are no match for GLB®. Our formulas work hard to remove and control stain-producing minerals from your water, protecting your pool surfaces from spring opening to winter closing.

GLB® Super Sequa-Sol® Sequestering Agent

This concentrated granular formula is specially formulated to protect pool surfaces from minerals in the water. It is ideal for use with hard water because it helps neutralize small quantities of stain-producing minerals such as iron, copper, or manganese that occur.

– Great for pool openings or when adding make-up water to the pool.

– Compatible with chlorine, ozone, salt water and mineral sanitizing systems.

Available Size: 2 lb.
