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 Seachems MultiTest: Marine pH & Alkalinity to check pH and total alkalinity.
Directions:
Use 1 capful (5 mL) for every 20 L (5 gallons) daily until pH stabilizes at 8.3.
(Note: The 2 & 4 L containers cap is 10 mL). This may take from a day to a week depending on original pH, alkalinity and buffer system balance. Thereafter, use as needed to maintain pH.
