Seachem Reef Buffer 50g – Safe pH & Alkalinity Stabiliser

Seachem Reef Buffer 50g is a reef-specific pH buffering supplement designed to safely raise and stabilize aquarium pH at the ideal reef level of 8.3 without the risk of dangerous overdosing. Unlike standard marine buffers that rely solely on sodium bicarbonate, Reef Buffer uses a precise blend of carbonate and bicarbonate salts, providing a higher effective buffering capacity.

With a pK of approximately 8.6 in saltwater, Reef Buffer is engineered to counteract the natural pH-lowering effects caused by organic acids produced in heavily stocked reef systems. This ensures greater pH stability compared to generic marine buffers, which often fail to reach optimal reef pH levels. When used as directed, Reef Buffer supports healthy coral growth, stable alkalinity, and long-term reef system balance.

Key Features:

• Safely raises reef aquarium pH to 8.3
• Reef-specific formula with carbonate & bicarbonate salts
• Higher buffering strength with pK ~8.6
• Prevents dangerous pH overshooting
• Increases alkalinity in a controlled manner
• Ideal for coral-dense reef systems
• Suitable for regular pH maintenance dosing
• Designed specifically for reef environments

Seachem Reef Buffer 50g is a precision-formulated buffering solution for reef aquariums requiring stable pH and alkalinity control. Its advanced salt blend delivers consistent results where standard marine buffers fall short, making it an essential tool for maintaining optimal reef water chemistry and coral health.
