Description
Maintain a thriving reef ecosystem with the purity of ESV Kalkwasser. A cornerstone of marine aquarium care for decades, Calcium Hydroxide is a proven, economical method for maintaining both calcium concentrations and alkalinity in closed marine systems. ESV’s formulation is meticulously refined to ensure the highest level of purity, meeting American Water Works Association and Water Chemical Codex requirements.
Why Choose ESV Kalkwasser?
Unlike standard industrial lime, ESV Kalkwasser is specifically processed for the sensitive environment of a reef tank. It serves a dual purpose:
-
Dual Maintenance: It provides ionic calcium for calcifying organisms (corals, clams, crustose coralline algae) while its hydroxide ions neutralize dissolved CO2, converting it into necessary bicarbonate and carbonate ions.
-
pH Elevation: By consuming dissolved carbon dioxide, Kalkwasser helps raise and stabilize aquarium pH, which is often suppressed in modern, indoor environments.
-
Phosphate Precipitation: Regular use can help precipitate phosphates out of the water column, aiding in the control of nuisance algae.

Mixing & Dosing Instructions
-
Preparation: Mix approximately 1 to 2 teaspoons of powder per gallon of RO/DI water.
-
Settling: Stir vigorously and allow the solution to sit until the "milkiness" settles, leaving a clear liquid (supernatant) at the top.
-
Application: Only the clear liquid should be added to the aquarium. It is best administered via a slow drip or through an Auto Top-Off (ATO) system to replace evaporated water.
-
Precaution: Never add the dry powder directly to the aquarium. Because of its high pH (approx. 12.4), it must be added slowly to avoid rapid fluctuations in the tank’s chemistry.
The ESV Advantage
When used in conjunction with ESV B-Ionic Magnesium, you can maintain a perfectly balanced ionic environment that prevents the precipitation of calcium carbonate on pumps and heaters, extending the life of your equipment and the health of your livestock.
