Seachem Reef Buffer Raises pH to 8.3 in Aquariums

Seachem Reef Buffer raises the pH of a reef aquarium to 8.3, without the risk of accidentally raising pH to a dangerous level. It will also raise alkalinity, allowing for greater stability in a reef system where the bioload is significantly greater than in a fish-only aquarium.

• Raises pH and carbonate alkalinity together
• Raises pH to 8.3 without risk of accidentally over-raising
• Allows for greater pH stability in reef systems with high bioload

Reef Buffer will raise pH and carbonate alkalinity. However, it is intended primarily to maintain a steady pH of 8.3 when pH maintenance is difficult. If pH maintenance is not an issue, Seachem Reef Builder or Reef Carbonate should be your first choice to supplement carbonate alkalinity.

Reef Buffer has a slightly higher pK than Seachem Marine Buffer. pK of a buffering agent is equivalent to the pH around which the buffer is most effective; Reef Buffers higher pK (8.6) provides greater stability in a reef system, where the bioload is greater than a fish-only system. The higher pK compensates for the organic acids produced by reef inhabitants, holding pH steady at 8.3.

Directions: 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 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 and carbonate additives are added on alternate days or at least 30 minutes apart.
