Seachem Reef Carbonate 500ml is a highly concentrated solution with a blend of carbonate and bicarbonate salts, designed to support the health of your reef aquarium by maintaining alkalinity levels. Essential for coral growth, this formulation helps stabilize pH levels around 8.3-8.4 in a closed reef system, unlike other products that may see pH levels fall below desirable ranges.

This product ensures that necessary elements such as calcium, magnesium, and strontium are not depleted during use, making it a reliable choice for maintaining a thriving marine ecosystem.
