Seachem Marine Buffer

Easy-to-use marine buffer safely raises and maintains a pH of 8.3. Contains a natural balance of sodium, magnesium, calcium, and potassium salts of carbonate, bicarbonate, and borate to enhance and maintain buffer capacity at pH 8.3 without sacrificing calcium. Special blended formula maintains both pH and alkalinity (KH) without disrupting the natural ionic balance of marine water even with prolonged use. Dissolves rapidly and does not obscure water clarity. Ideal for marine, brackish or alkaline freshwater aquariums. 250 grams treats up to 1,000 gallons.

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.

Directions for Use:
Add 5 g (1 level teaspoon) for each 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 approximately 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.

Helpful Hints:
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.
