Reef Buffer™ will also raise carbonate alkalinity; however,
it is intended primarily for use as a buffer in a reef system where the
maintenance of a pH of 8.3 is often difficult. When pH is not an issue,
Reef Builder™ or Reef Carbonate™ should be your first choice for a
carbonate alkalinity supplement.
Reef Buffer™ is specifically designed to meet the needs and
requirements of the closed reef environment. The principal difference
between Reef Buffer™ and Marine Buffer™ is that the pK of Reef Buffer™
is slightly higher than that of Marine Buffer™. The pK of a buffering
agent is equivalent to the pH around which that buffer most strongly
buffers. One would presume, then, that the pK of a saltwater buffer
should be 8.3; however, the multitude of organic acids produced by the
inhabitants of a reef system forces pH downward to a much greater degree
than in a non-reef, marine system. A buffer with a pK of 8.3 would end
up yielding a pH more in the range of 8.0-8.2. Reef Buffer's ™ higher pK
(8.6) allows for greater pH stability in a reef system where the
bioload is significantly more than in a fish only system. Competing
products are not designed specifically for the reef environment; the pK
is too low (in most cases, pK 8.3). At this pK, the proper pH can never
be reached in saltwater.

Check pH and alkalinity before use. 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
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.
