- Protection at every tap, not just one faucet
- Serviceable, refillable media bed

How it works
Catalytic carbon adsorbs chlorine, chloramine and organic chemicals, and the valve backwashes the bed so it does not channel or clog.
Media benefits
Catalytic carbon
- Removes chlorine and chloramine: no pool smell or taste at any tap
- Catalytic grade removes chloramine faster and more completely than plain carbon
- Reduces many organic chemicals and VOCs
- Backwashing keeps the bed from clogging or channeling, so it lasts for years

| Media | Named media, exact amount for each size (listed above) | Media type or amount often not stated |
| Delivery | Ships pre-built, ready to install | Often ships in pieces for you to assemble and load |

Fleck Algal Toxins (Cyanotoxins) System
A complete Fleck system — control head valve, tank and the right media — engineered to solve algal toxins (cyanotoxins) for good.
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
