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 Seachem’s MultiTest: Marine pH & Alkalinity™ 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. If this practice is not adequate, then overstocking, overfeeding, or other poor management practice should be sought as a likely cause. In ionically balanced marine water, Marine Buffer™ produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Buffer™ that does not dissolve within ~15 minutes, then poor ionic balance was present. A water change should be initiated when convenient before further use of the product. Effectiveness improves with continued use. Do not directly mix with any calcium, magnesium, or strontium supplement.
