Marine Bufferª will safely raise marine pH to 8.3. It will not raise pH above 8.3 even if inadvertently overdosed. Marine Bufferª 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 Bufferª contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. Use Seachem's MultiTest: Marine pH & Alkalinityª to check pH and total alkalinity. Use Marine Traceª 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 Bufferª produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Bufferª 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.
