Keep your aquarium water at its best by using the E.S.V. Calcium Hydroxide regularly. Calcium Hydroxide from Pet Store
, also known as Kalkwasser Powder, effectively maintains the calcium level and alkalinity of the aquarium water in closed reef tanks. Calcifying organisms in the tank directly feed on the calcium of this special powder. The hydroxide ions in the powder react to the dissolved carbon dioxide in the water and transform it into carbonate and bicarbonate ions. These in turn are used by the calcifying organisms in the aquarium. As a result, ionic imbalances due to extended use of other calcium supplements like calcium chloride are avoided.
The E.S.V. Calcium Hydroxide is a safe and pure substance that has passed the highest standards for safety and effectiveness. It is widely used by water organizations even in potable water. It is easy to use. Just add two teaspoons of the E.S.V. Calcium Hydroxide for every gallon of freshwater. Add the mixture slowly to your aquarium
The E.S.V. Calcium Hydroxide is also economical. This powder contains high pH levels, allowing you to utilize only a small amount to experience its efficacy. For best results, use the "dripping method" in order to avoid alkalinity loss and localized precipitation. The E.S.V. Calcium Hydroxide comes in a four-pound pack for your convenience.
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.
