Kalkwasser - Translates from the German for limewater and is a solution made by dissolving Calcium Hydroxide in water. The resultant fresh solution is alkaline with a pH of 12.4 and contains a ready supply of both Calcium ions and Carbonate ions.

The solution reacts readily with CO2 in the atmosphere to form calcium carbonate and so it must be made in a relatively air tight environment which is where the kalkwasser stirrer comes in to play.

The KM800 is a stirrer suitable for larger tanks and commercial systems holding up to 2kg of calcium hydroxide and producing 30lt - 6.7 UK gallons - 7.5 USG per hour of kalkwasser.
