Reef Code B is the carbonate-bearing component of a specialized two-part dosing system designed to increase calcium and alkalinity in saltwater aquariums while maintaining the precise ratio found in natural seawater. This liquid supplement provides the essential buffering capacity needed by reef-building organisms such as corals, clams, and calcareous algae to maintain healthy skeletal growth and metabolic functions. By adding carbonates directly to the water column, it simplifies the complex task of stabilizing pH levels and supporting long-term reef health without introducing unwanted contaminants.

This formula is ionically balanced with Reef Code A to ensure that calcium and carbonate ions are added in exact natural proportions when dosed in equal amounts. It is significantly stronger than many competing products on the market, allowing for efficient treatment of large volumes of water with minimal dosage requirements. The product contains absolutely no phosphate, silicate, or organic material, ensuring it does not fuel nuisance algae growth. Each milliliter increases alkalinity by approximately 2.22 dKH in one gallon of water, and users must allow a minimum of sixty seconds between dosing this product and its counterpart to prevent precipitation.

This system is best suited for advanced reef keepers and large public aquariums that require precise control over water chemistry to support dense coral populations. It is ideal for aquarists using calcium reactors or Kalkwasser who need a reliable backup or primary method to maintain alkalinity within the 7 to 12 dKH range without introducing excess salts. By eliminating the guesswork of balancing two separate parameters, this product allows hobbyists to focus on colony expansion and coloration while ensuring their livestock receives the exact mineral composition they require for optimal survival.
