Seachem Reef Carbonate 250 mL
Seachem Reef Carbonate is a concentrated carbonate buffer designed to safely raise and maintain alkalinity (KH) and stabilize pH in reef and marine aquariums. Proper carbonate levels are essential for coral skeletal growth, pH stability, and overall reef health, especially in systems with high coral demand.
Reef Carbonate is ideal for reef keepers who need fine control over alkalinity without introducing unnecessary ions, making it a valuable tool for SPS, LPS, and mixed reef systems.
The 250 mL bottle is perfect for nano to medium reef aquariums or targeted alkalinity adjustments.
