Product Information




Seachem Marine Buffer 20 kg (44 lbs).

Marine Buffer will safely raise marine pH to 8.3. It will not raise pH above 8.3 even if inadvertently overdosed. Marine Buffer is a blended product and is not just sodium bicarbonate or sodium carbonate, commonly sold as a substitute. Such products can raise pH to dangerous levels if not used properly.

Marine Buffer contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. Use Seachems MultiTest: Marine pH to check pH and total alkalinity. Use Marine Trace to restore the proper level of trace elements required by thriving, healthy saltwater fish.

DIRECTIONS: Add 5 g (1 level teaspoon) for each 80 L (20 gallons). Dissolve in at least one cup of freshwater. This dose will also raise alkalinity by about 1 meq/L. Add daily until pH stabilizes at 8.3. This will take from a day to a week, depending on original pH and alkalinity. Thereafter, use biweekly or monthly to maintain a pH of 8.3.
