Seachem Reef Carbonate is a premium-grade alkalinity supplement formulated to raise and maintain carbonate alkalinity (KH) in reef aquariums. It contains a balanced blend of carbonate and bicarbonate salts, delivering a pK of ~9.0 in saltwater—higher than competing products—ensuring stable pH around 8.3–8.4.
Carbonates are essential for coral calcification and skeletal growth. A deficiency in carbonate alkalinity can halt coral growth and lead to rapid health decline. Reef Carbonate is phosphate-free and will not promote algae growth or cloud the water. It is safe for all marine organisms and will not deplete calcium, magnesium, or strontium when used as directed.
