Raises pH to 8.3
Raises pH and carbonate alkalinity together
pK (8.6) allows for greater pH stability
Seachem 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.
Seachem 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.

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.
