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.
Reef alkalinity should be maintained at 3–5 meq/L (8–14 dKH). Alkalinity should not be allowed to fall below 2 meq/L.
