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 KM500ST is a stirrer suitable for larger tanks up to 6700 lts - 1500 UK gallons - 1800 USG and will produce up to 10lt - 2.6 USG of kalkwasser per hour.
Supplied with 500ml tub of RowaKalk
