  • Carbonates and calcium are essential to all coral growth
  • Reef Builder will not deplete calcium, magnesium, or strontium
  • Reef Builder and Reef Buffer may be used together

Reef Builder raises carbonate alkalinity without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3.

Use Reef Buffer to raise carbonate alkalinity and pH. 

Use 3 g (half a level teaspoon*) per 150 L (40 gallons*) twice a week. Dissolve in at least 250 mL (1 cup*) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly.
