Jack's Magic The Emerald Stuff - 32 oz

The Emerald Stuff (Four-by-One Clarifier) produces super clear water fast through a highly effective "4 x 1” action: the rich green emerald formulation combines a powerful clarifier, sequestrant, chelating agent, and flocculent in one convenient product.

The emerald stuff requires no premixing, will not affect ph, and is compatible with all swimming pool sanitizer systems.

The emerald stuff removes oils, soaps, metals, cosmetics, and other particulate matter that can cause staining, cloudy water, and discoloration.

The emerald stuff also increases filter efficiency.
