Scale & Corrosion Control Media

Slow Dissolving Poly Phosphate in Bulk 25 lbs.

Food-grade phosphate crystal media engineered for gradual release in tank-style applications to sequester hardness minerals and prevent scale formation
25 lb. Bulk Pack Crystal Ball Form Food Grade Scale Inhibitor
This bulk 25 lb. pack of slow dissolving poly phosphate crystals is designed for installation in dedicated phosphate feeders or media tanks where controlled release is critical. The crystalline ball format dissolves gradually as water passes through, releasing phosphate compounds that sequester calcium and magnesium ions to prevent scale buildup in pipes, water heaters, and appliances.
HOW IT WORKS

Phosphate Sequestration Process

1
CONTACT

Water Enters Media Bed

Untreated water flows through the phosphate crystal bed, making contact with the slow-dissolving polyphosphate balls in your feeder tank or cartridge housing.

2
DISSOLUTION

Controlled Phosphate Release

The slow dissolve formulation releases phosphate ions gradually into the water stream, ensuring consistent dosing without over-feeding or sudden spikes in phosphate concentration.

3
SEQUESTRATION

Hardness Mineral Binding

Released polyphosphate compounds bind with dissolved calcium and magnesium ions, holding them in solution and preventing them from precipitating as scale on heating elements and pipe walls.

4
PROTECTION

Scale and Corrosion Prevention

Treated water exits with sequestered hardness minerals, reducing scale formation in water heaters, boilers, and plumbing while forming a protective film that minimizes corrosion in metal piping.

COMPATIBILITY

Recommended Applications

This slow dissolving poly phosphate media is suitable for use in dedicated phosphate feeder tanks, inline phosphate cartridge housings, and custom scale prevention systems. Ideal for whole-house applications, commercial water heaters, boiler feedwater systems, and anywhere scale formation or metal corrosion is a concern. Not a substitute for water softening where zero hardness is required, but effective for threshold scale inhibition in applications where some mineral content is acceptable or preferred.
