One is a revolutionary calcium supplement for reef aquariums containing balanced levels of calcium, alkalinity and magnesium. It is a complete calcium system in a single bottle.

Traditional calcium supplementation methods such as calcium reactors and two-part systems can be confusing and troublesome. Additionally, they often require extra steps to correct ionic imbalances.

One was designed with simplicity and convenience in mind. Every addition made with One ensures balanced levels without building up any unwanted residual ions.

Proper dosing with One maintains water parameters of:

400 ppm Ca

1300 ppm Mg

7 dKH


  • Phosphate and silicate free
  • Does not elevate salinity
  • No residual ion build up over time
  • Does not contain insoluble calcium carbonate
  • Maintain pH around 8.1 - 8.2

Size: 500 mL

How does One work:

One is engineered from two forms of acetate and hydroxide salts. It contains calcium ions, magnesium ions and acetate ions. When dosed, the calcium and magnesium ions are freely available for uptake by corals, clams and other reef organisms. The acetate ions are promptly metabolized by bacteria to create biologically available bicarbonate. This process provides alkalinity to your reef aquarium. The hydroxide salts in our product are present to help maintain a higher pH as well as to provide more alkalinity.

Shake bottle thoroughly before each use.

Daily Dosing:

To obtain maximum tank stability, we highly recommend daily dosing. For every 50 gallons of total aquarium volume, dose 1-4 capfuls (5-20mL) in an area with good flow and away from direct contact with corals. Sumps are an ideal dosing location.

Refer to chart for details.
