Product details
Marine Buffer – SeaChem is a blended marine aquarium buffer formulated to safely raise and hold seawater pH at 8.3. It’s designed for use in marine systems where alkalinity and the buffering capacity of the water need to be stabilized during day-to-day maintenance and water changes. Rather than acting like a simple bicarbonate or carbonate-only substitute, Marine Buffer – SeaChem uses a formulated blend of buffering components to support a steadier pH set point for reef and other marine setups.
Features:
- Safely raises marine pH to 8.3.
- Helps prevent pH from rising above 8.3 even if overdosed.
- Blended buffer formulation (not just sodium bicarbonate or sodium carbonate).
- Uses carbonate/bicarbonate/borate buffering chemistry to improve pH stability as buffering demands change with water changes.
- Contains a mix of salts including sodium, magnesium, calcium, strontium, and potassium components associated with the buffer blend.
- Built around alkalinity buffering concepts involving carbonate, bicarbonate, and borate ions to resist unwanted pH swings.
Specifications:
- Product name: Marine Buffer – SeaChem
