Reef Buffer™ is intended primarily for use in a reef system where the maintenance of a pH of 8.3 is often difficult. 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.
Reef Buffer™ will also raise carbonate alkalinity. Reef Buffer™ is a blended product and is not just sodium carbonate.
Reef Builder™ should be used to raise alkalinity when pH is not a problem. Use Seachem’s MultiTest: Marine pH & Alkalinity™ to check pH and total alkalinity.

Check pH and alkalinity before use. Use 5 g (1 level teaspoon) for every 150 L (40 gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L).
Dissolve in at least 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 (calcium does not need to exceed 400 mg/L).

    this raised the ph on my tank. it works! (Posted on 2/7/2017)

  2. works well Review by vi
    Product Rating:

    i was dosing this every day to keep my ph up. it works. some advice: if you add this and notice your kh raises to 12 but the ph stays low then make sure your salt is at 1.026. next make sure you have 1 part calcium to 3 parts magnesium. my cal is 420 and mag 1260. if the problem persists then you need to attach a carbon dioxide scrubber filter to the air intake of your protein skimmer. the protein skimmer adds carbon dioxide to the water and high CD lowers ph. your ph will come up to 8.1-8.3. this stuff works (Posted on 1/27/2017)
