Seachem Marine Buffer is the original and still unique buffer with a pH of 8.3, designed to adjust pH to 8.3 and maintain both pH and alkalinity at steady levels. It is formulated not to disrupt the natural ionic balance of saltwater with prolonged use. Marine Buffer contains a natural balance of sodium, magnesium, calcium and potassium salts of carbonate, bicarbonate, and borate, formulated for enhanced and lasting buffer capacity at pH 8.3 without sacrificing calcium. It dissolves readily and does not obscure water clarity.
Add 1 teaspoon for each 20 gallons of water. Dissolve in at least 1 cup of freshwater before pouring in tank. Add daily until pH stabilizes at 8.3.
Size: 50 grams (Treats up to 200 gallons of water)
