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.

400 ppm Ca
1300 ppm Mg
7 dKH


Phosphate and silicate free
Does not elevate salinity
No residual ion build up over time
