Jack's Magic The Magenta Stuff (1 qt) 4 Pack | Metal Stain & Scale Control for Pools

Overview

Jack's Magic The Magenta Stuff is a versatile pool treatment designed to prevent and reduce metal staining and scale buildup. Its potent liquid formula acts as a sequestering agent, helping metals and calcium stay in solution so your filter can remove them more efficiently. The result is water that looks clearer and surfaces that stay healthier over time.

In addition to stain control, The Magenta Stuff supports plaster startup workflows by reducing dust, a common challenge when a pool is first filled or resurfaced. The product is compatible with every sanitizer system, including saltwater setups, so you can integrate it into your existing routine without changing chemistry.

A notable feature is Phos-Stop Plus, a unique additive that adds no phosphates to the pool and, in fact, helps lower phosphates already present. Lower phosphate levels can help minimize algae growth opportunities and keep water balance more stable.
