Product Overview

A proven choice for protecting salt cells and managing plaster dust during new pool start-ups.

Jack's Magic formulated this 32 fl oz. sequestering agent specifically for high-performance environments like saltwater pools. It reliably handles metal staining and scale buildup without adding any phosphate to the water, which is a critical consideration for modern pool chemistry. In our experience, it is the standard specification for technicians looking to extend the life of salt chlorine generator cells by preventing calcium scale on the plates.

Why Pool Pros Trust This

Benefits & What Makes It Different

Phosphate-Free Composition

Unlike many sequestering agents, this formula will not yield any phosphate, keeping your water chemistry easier to balance and preventing nutrient spikes.

Salt Cell Protection

Specifically engineered to prevent scale accumulation on salt chlorine generator electrodes, which helps maintain efficient chlorine production and extends cell life.

Plaster Dust Control

For homeowners running a new pool start-up, this product helps keep plaster dust in suspension so it can be filtered out rather than hardening on the finish.

Common Questions & Instructions

Will The Magenta Stuff affect my pool's phosphate levels?

No, The Magenta Stuff is specifically formulated not to yield any phosphate, which is essential for pool owners who want to avoid contributing to potential algae growth while managing metals.
