Reef Builder raises carbonate alkalinity (KH) without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3. Used as directed, Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity.

KEY FEATURES:

Raises carbonate alkalinity (KH) with minimal impact on pH
A blend of carbonate sources that will not lower pH as competing bicarbonate only products can
Will not deplete calcium, magnesium, or strontium

DIRECTIONS:
Beginner
Use 3g (1/2 level teaspoon) per 150L (40 US gallons) twice a week. Dissolve in at least 250mL (1 cup) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly. For precise dosing, use the Seachem Digital Spoon Scale.

Advanced
Check alkalinity, then follow addition regimen above until alkalinity is adjusted to 3-6 meq/L (8-17 dKH). Each 3 g/150 L will raise alkalinity by about 0.25 meq/L. Quantity or frequency can be adjusted, but do not exceed 12 g/150 L per day. Thereafter, use as required to maintain alkalinity.
