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. Use Marine Trace to restore the proper level of trace and feed NutriDiet Marine Flakes for thriving, healthy saltwater fish Sold in Qty of: 1
