Seachem Reef Builder™ is a specialized powdered supplement designed to raise carbonate alkalinity (KH) in reef aquariums without immediately impacting pH+. While traditional buffers can cause sudden pH spikes, Reef Builder™ uses a unique blend of carbonate sources that stabilize pH at 8.3 with long-term use. It is specifically formulated to provide the essential carbonates required for coral skeletal growth while ensuring that critical elements like calcium, magnesium, and strontium do not precipitate out of the water column.
Reef Builder™ provides a high-capacity solution for maintaining the stable ionic environment necessary for a thriving reef.
Minimal pH Impact: Unlike bicarbonate-only products that can lower $pH$, this balanced formula raises alkalinity while maintaining a steady acid-base balance.
Supports Calcification: Supplies the inorganic carbon building blocks that stony corals and coralline algae need to build their skeletons.
Ionically Balanced: Formulated with carbonate, bicarbonate, chloride, and sulfate salts of sodium, magnesium, calcium, and potassium to prevent ionic drift.
High Concentration: Each gram contains a minimum of 12 meq of alkalinity, making it a highly efficient and cost-effective choice for large systems.
No Precipitation Risk: When used as directed, it will not deplete calcium or magnesium, which are often lost when using lower-quality alkalinity boosters.
How much Seachem Reef Builder™ should I use?
Beginner: Use 3 g (1/2 level teaspoon) per 150 L (40 gallons) twice a week. Dissolve the powder in at least 250 mL (1 cup) of freshwater before adding to the tank.
What is the difference between Reef Builder™ and Reef Buffer™?
Reef Builder's primary function is adjusting alkalinity without affecting pH. Reef Buffer™ is intended to raise both alkalinity and pH simultaneously when pH levels are low.
Can I mix this with my calcium supplement?
No. Do not directly mix Reef Builder™ with calcium, magnesium, or strontium supplements in the same container, as they will precipitate. It is best to add them on alternate days or at least 30 minutes apart.
