Seachem Reef Buffer™
Raises pH to 8.3
Raises pH and carbonate alkalinity together
pK (8.6) allows for greater pH stability in a reef system where the bioload is significantly more than in a fish only system
OVERVIEW
When used as directed Reef Buffer™ will raise the pH of your reef system to 8.3 without fear of accidentally overshooting the pH to a dangerous level. Whereas competing products simply use sodium bicarbonate, Reef Buffer™ is made with a blend of carbonate and bicarbonate salts. This blend of salts results in Reef Buffer™ yielding a pK of roughly 8.6 in saltwater.

DIRECTIONS
Dosage Calculator
Check pH and alkalinity before use (use MultiTest™ Marine pH & Alkalinity to test ph nd alkalinity levels). Use 5 g (1 level teaspoon) for every 150 L (40 US gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L). For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 mL (one cup) of freshwater, then add to the tank. The pH of natural sea water is 8.25–8.30. In a well established reef system pH adjustment may be necessary biweekly to semiweekly. Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L).

If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained or substantial cloudiness that does not clear within 15 minutes is encountered, then the system is not ionically balanced. To restore ionic balance perform a water change or adjust the magnesium and calcium levels to approximately 3:1 Mg:Ca.

DO NOT OVERDOSE: Excess alkalinity may enhance the loss of calcium, magnesium, and strontium. Do not directly mix with any calcium, magnesium, or strontium supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart.
