Highly-effective alkalinity-increasing (buffer) powderedblend for all marine and reef aquariaHelps increase pH stability in an aquarium by raising thealkalinity; continued addition raises pH until 8.3 is reached, atwhich point the pH remains unchanged and the alkalinityalone increasesProvides a source of carbonates, which make up the majorityby weight of aragonite, the mineral secreted by reef-buildingorganisms as skeletal materialFormulated by a marine scientist
