Seachem 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.Features: Raises and maintains pH at 8.3 in all saltwater aquariumsCan be used safely in reef tanksContains borate for added stabilityContains magnesium to alleviate precipitation effectsIntended For: Reef Aquariums Instructions: Add 5 g (1 level teaspoon) for each 80 L (20 US gallons). For precise dosing, use the Seachem Digital Spoon Scale. 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.
