Fleck Algal Toxins (Cyanotoxins) Filter

The Fleck system that solves it

This is a full Fleck system built on three parts that work together: a genuine Fleck 5600 SXT backwashing control valve on top of a whole-house adsorption tank, filled with the media matched to your water. The valve backwashes the bed on schedule to keep flow strong and the media working — no cartridges to change. One consistent Fleck platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.

What it does for your home

• Removes algal toxins from your water
• Whole-house reduction of the target contaminant
• Protection at every tap, not just one faucet
• Serviceable, refillable media bed
• Self-backwashing valve keeps the bed active
