Seachem Reef Buffer for Aquarium Water Care
Seachem Reef Buffer is an aquarium water care product designed specifically for reef systems. This 250 g buffer raises both pH and carbonate alkalinity, ensuring optimal conditions for aquatic life. With a pK of 8.6, it provides enhanced pH stability, crucial for maintaining a healthy reef environment.
This product is essential for aquarists managing closed reef systems, where maintaining a stable pH of 8.3 can be challenging. Reef Buffer effectively counters the downward pH shifts caused by organic acids from reef inhabitants. Unlike Marine Buffer, which has a lower pK, Reef Buffer's formulation is tailored to meet the unique demands of a reef ecosystem. It is recommended to use Reef Builder or Reef Carbonate when pH is not a primary concern.
Key Features
- Raises pH to 8.3
