Seachem Marine Buffer 250g – Stabilises Marine pH to 8.3

Seachem Marine Buffer 250g is a professional-grade pH buffering solution designed specifically for marine and reef aquariums. It safely raises and stabilises aquarium pH at 8.3, the ideal level for saltwater systems, without the risk of dangerous overcorrection—even if overdosed.

Unlike simple bicarbonate or carbonate substitutes, Marine Buffer is a carefully balanced blend of carbonate, bicarbonate, and borate salts combined with essential elements such as calcium, magnesium, strontium, sodium, and potassium. This advanced formulation improves buffering capacity, enhances alkalinity stability, and resists pH swings caused by water changes, overstocking, or biological load.

Marine Buffer was the first marine buffer to include borate salts, making it one of the most stable and effective pH control solutions available for marine aquariums today.
