The Seachem Liquid Marine Buffer is engineered to maintain a stable and safe pH level of 8.3 in marine aquariums. This innovative solution is chemically blended with sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. Unlike other sodium bicarbonate or sodium carbonate-based products, this buffer will not elevate pH beyond the recommended level, even if accidentally overdosed.

Designed to work in tandem with regular water changes, Liquid Marine Buffer utilises a calculated pK slightly above 8.3 to counterbalance the new bicarbonate influx, ensuring consistent pH control with each application.

• Keeps aquarium pH stable at 8.3, preventing harmful fluctuations.
• Safe for use, with a formulation that avoids over-alkalisation.
• Blended salts include essential elements such as calcium and magnesium.
• Smooth integration with existing marine buffer systems.
• Easy dosage instructions for reliable application.

Liquid Marine Buffer offers a dependable method to master the chemistry of your marine aquarium. Its balanced composition supports not only the pH stability but also contributes vital compounds required for healthy marine life.

• Volume: Available in 500 mL, 2 L, and 4 L bottles
• Dosage: 5 mL per 20 L of water
• Container cap size: 10 mL for 2 & 4 L bottles
