How template-assisted
crystallization works.
Hard water flows through TAC media
Water containing dissolved calcium and magnesium passes through a tank of template-assisted crystallization nucleation sites — tiny polymer beads with a specific surface structure.
Minerals crystallize into micro-particles
The TAC sites cause dissolved hard minerals to form stable, microscopic crystals. These crystals remain in the water but can no longer attach to surfaces — scale formation stops completely.
Conditioned water protects your home
The mineral crystals pass harmlessly through your pipes, fixtures, and appliances without depositing scale. No salt. No chemicals. No brine waste. The system runs indefinitely with no refills.

The technology
Food-grade phosphate.
Better than TAC.
Most no-salt systems use TAC (template-assisted crystallization). We stopped using it. Food-grade phosphate is a sequestering agent that binds calcium and magnesium ions so they can't deposit on pipes, fixtures, or heating elements. Higher performance. Zero media degradation.
Traditional TAC
- Crystallization media
- Performance drops after 18 to 24 months
- Media replacement required
- Lower scale resistance at higher hardness
- Sensitive to chlorine
Food-Grade Phosphate
- Ion sequestration
- Consistent performance for the life of the cartridge
- Annual cartridge swap only
- Handles higher hardness without drop-off
- Chlorine-tolerant core
Food-grade phosphate is FDA-approved for drinking water systems. It's used by municipalities worldwide to prevent corrosion and scale in pipe networks. In your home, the same science keeps scale off your fixtures.

Quintex 5 + Carbon
The Quintex 5 paired with a carbon pre-filter. Conditions hard water and strips chlorine, chloramine, taste, and odor in one footprint. The most complete no-salt setup for city water.
- Food-grade phosphate conditioning
- Full chlorine and chloramine removal
- Taste and odor reduction
- Single install footprint
Water Conditioner Cartridge
Replaceable food-grade phosphate cartridge for use inside the AiO or other Aqua Otter housings. Ideal for well water setups where you want no-salt conditioning alongside iron and sulfur removal.
- Drop-in cartridge format
- Compatible with AiO housings
- Annual replacement only
- Pairs with well water systems
“Best purchase we have made. No issues in over three years. No salt to buy, no maintenance, and our fixtures look brand new. It just works and you never have to think about it.”
