Liquid Marine Buffer, 4 L / 1 fl. gal.
Liquid Marine Buffer will safely raise marine pH to 8.3 while adjusting alkalinity. It will not raise pH above 8.3 even if inadvertently overdosed. Liquid Marine Buffer contains a balanced blend of bicarbonate, carbonate and borate salts designed to raise pH and restore disrupted buffer systems to the proper balance. Use Seachem's MultiTest: Marine pH & Alkalinity to check pH and total alkalinity.
