Iron and sulfur are two of the most common elements found in nature. While vital for everyday life, they are an absolute nuisance in household water supplies—costing you money in appliance damage and constant maintenance frustration.

Stubborn iron leaves ugly reddish-orange staining on sinks, tubs, and plumbing fixtures, while making laundry dingy and discoloring hair. Iron bacteria can also cause a slimy buildup in standing water (like toilet tanks) that smells like rotting vegetation. Meanwhile, sulfur is instantly recognizable by its distinct, unappealing rotten egg odor and associated yellow tinting.

The Fleck AIO single-tank setup is a highly efficient and cost-effective way to neutralize impurities without needing external, noisy air compressors or chemical pumps.

The system maintains a pressurized pocket of fresh air at the very top of the mineral tank while in service. As raw water flows through this compressed air pocket, the dissolved iron and sulfur are instantly oxidized out of solution.

An automatic daily backwash sequence flushes the trapped minerals straight down the drain, cleanses the advanced Katalox filter media bed, and replenishes the system with a fresh pocket of compressed oxygen.

By utilizing a patented piston in the control valve, the AIO packs the entire multi-stage oxidation sequence inside a single tank, keeping your maintenance costs and system downtime down to a minimum.
