Seachem Reef Carbonate is a concentrated (4,000 meq/L) optimized blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in reef aquariums. Alkalinity is critical for the stability of $pH$ and provides the essential inorganic carbon required for the calcification of corals and other reef-building organisms. Reef Carbonate is formulated to provide a bio-available source of carbonates without impacting calcium levels or causing immediate precipitation.
Reef Carbonate is engineered to simplify the management of reef chemistry while ensuring long-term ionic balance.
High Concentration: A powerful 4,000 meq/L formula, offering a cost-effective solution for maintaining alkalinity in heavily stocked reef systems.
$pH$ Support: While its primary function is to boost alkalinity, it also provides the necessary buffering capacity to prevent dangerous $pH$ swings.
Bio-Available Carbonate: Delivers carbonates in a form that is immediately accessible for coral skeletal growth and calcification.
Ionic Stability: Specifically blended to work in harmony with calcium and magnesium supplements, reducing the risk of "snowstorms" or mineral precipitation.
Safe for All Inhabitants: Completely safe for all marine fish, corals, and invertebrates when used as directed to reach target levels.
What is the ideal alkalinity for a reef tank?
Natural seawater is approximately 2.5 meq/L (7 dKH). Most reef keepers aim for a range between 3.0 and 5.0 meq/L (8.4–14 dKH) to encourage faster coral growth.
How do I dose Seachem Reef Carbonate?
Use 5 mL (1 capful) per 80 L (20 US gallons) twice a week. It is best to check your alkalinity with a test kit before and after dosing to determine your tank's specific consumption rate.
Can I mix this with Reef Complete (Calcium)?
No. Like all alkalinity and calcium supplements, they should be dosed at different times or in different areas of high flow to prevent them from reacting and precipitating out of the water.
Seachem Reef Complete: The essential calcium companion to Reef Carbonate for balanced coral calcification.
Seachem Reef Advantage Magnesium: Maintains the ionic link that allows your alkalinity and calcium to stay dissolved in the water column.
Seachem MultiTest Marine pH & Alkalinity: A high-precision kit for accurately monitoring the parameters managed by Reef Carbonate.
