Seachem Reef Buffer – High-pK pH Stabilizer for Reef Aquariums

Seachem Reef Buffer is a specialized buffering agent specifically designed for the reef environment, where the demand for pH stability is exceptionally high. While standard buffers are designed for community marine tanks, Reef Buffer features a higher pK (8.6) to effectively combat the significant organic acid production common in heavily stocked reef systems. It is the premier tool for raising and maintaining pH at 8.3 while simultaneously increasing carbonate alkalinity.

Advanced Carbonate Supplementation & pH Lock

Reef Buffer is engineered to provide a more aggressive buffering capacity than standard marine salts.

High pK Value: A pK of 8.6 allows this buffer to hold a stable pH of 8.3 even in systems with high biological loads that naturally pull pH downward.
Dual Action: Increases both carbonate alkalinity and pH, providing the essential carbon source needed for coral calcification.
Enhanced Stability: Specifically formulated to prevent the sudden pH "swings" that can cause stress or tissue loss in sensitive SPS and LPS corals.
Blended Formulation: Contains a precise mix of carbonate, bicarbonate, and borate salts to optimize the ionic balance of reef water.
No Impact on Calcium: Designed to work alongside calcium supplements without causing immediate precipitation when dosed correctly.

FAQ Section: Common Questions

How is Reef Buffer different from Marine Buffer? Marine Buffer is designed to lock pH at 8.3 and is best for fish-only systems. Reef Buffer has a higher pK, making it more effective at raising pH to 8.3 in reef tanks where high organic loads make it difficult to maintain alkalinity.
What is the correct dosage for Reef Buffer? Check your pH and alkalinity first. Use 5 g (1 level teaspoon) per 150 L (40 US gallons) to raise pH by about 0.1 units. Dissolve in freshwater before adding to a high-flow area of the tank.
Will this raise my salinity? In very small amounts, yes, as it adds dissolved salts to the water. However, at standard dosing levels, the impact on specific gravity is negligible.
