Seachem Reef Builder

Free Shipping at $75

Sea Chem 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. Carbonates and calcium are essential to all coral growth.

  • Raises carbonate alkalinity
  • Does not immediately impact pH
  • Promotes healthy coral growth


If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Sea Chem Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity.

Sea Chem Reef Builder and Reef Buffer may be used together. Use Sea Chem Reef Builder to raise carbonate alkalinity without affecting pH. Use Reef Buffer to raise carbonate alkalinity and pH.

500 g treats 32,000 L (8,000 gallons). Use 3 grams per 40 gallons twice a week and check alkalinity every 2 weeks and adjust amount or frequency accordingly.
