Calcium Hydroxide is the proven standard for maintaining calcium concentration
and alkalinity in closed marine aquaria. The calcium provided is directly
used by calcifying organisms, and the hydroxide ions provided readily
convert dissolved CO2 into bicarbonate and carbonate ions, which are also
directly used by calcifying organisms. The net result is no ionic imbalances
in the aquarium water, which can occur through the prolonged use of other
calcium supplements, such as calcium chloride.
Our product is extrmely pure and meets American Water Works and Water
Chemicals Codex Specifications. This means it's pure enough to be used
in low-levels as potable water additive by water municipalities. Due to the
high pH of Calcium Hydroxide solutions, it's important to add slowly ("dripping"
is best) to your system so as to prevent localized precipitation and the resultant
loss of alkalinity. Our packaging includes lot number, date tested, and
the date filled. We also provide complete instructions for use.
