Marine Buffer will safely raise the pH in marine water to 8.3. It will not raise pH above 8.3 even in the case of accidental overdose. Marine Buffer is a product blend and not just sodium bicarbonate or sodium carbonate, which are commonly sold as substitutes.

Key Features:

• Raises and maintains pH at 8.3 in all saltwater aquariums
• Can be safely used in reef aquariums
• Contains borates to enhance stability
• Contains magnesium to mitigate precipitation effects

Directions:
Add 5 grams (one level teaspoon) for every 80 liters (20 US gallons). Dissolve the amount in at least one cup of fresh water. This dose will also raise alkalinity by approximately 1 meq/L. Add daily until pH stabilizes at 8.3. This may take from a day to a week, depending on the initial pH and alkalinity. Thereafter, use biweekly or monthly to maintain pH at 8.3.
