Description

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. This product is extremely 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. Use two teaspoons of Calcium Hydroxide Powder per gallon of top-off fresh water.

Best Calcium by SAUL SADOWSKY

Experience Level: Expert

Posted on 7/19/2007 from CHANDLER, AZ UNITED STATES

Comments: This product "rocks" we have used only this type of calcium Hydroxide from Marine Depot for our 1000 g reef tank which has been running since mid Feb 2007 and the growth of not only coraline algae but the SPS corals is phenomenal. There is no need for 2 part dosing with this product; Alkalinity levels are always maintained with just adding this product. We get comments every week form reef enthusiasts throughout Arizona.
Yes, I would recommend this product to my friends.
