Deltec KM Kalkwasser Stirrer Information




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 KM500T is the standard stirrer suitable for tanks up to 1500 lts (350 UK gallons) and will produce up to 5lt of kalkwasser per hour.

WOW, what a machine Product Review by SILAS (Posted on 2/26/14)
Rating
Excellent!

Comments: First I thought why should I spend that much money for a stirrer, after talking to a few expert and now using it for a week or so, I can see why. This stirres instead of using power head type pump to "mix" the kalkwasser. The solution entering the tank does not contain undissolved lime where the power head pump design may. The built quality is good, well thought out. The hose that connects between the lower bulkhead and exit nozzle assembly should be hard plumb to reduce an area of failure. Other than that, other than the cost, it is a great machine.

700 usd tube with stick Product Review by DREW YOUNG (Posted on 1/27/09)

Comments: While this is a simple design that is superior to any device subjecting kalk to an impeller it is just plain offensive to charge 500 dollars for a tube with a stick requiring proprietary replacement parts. It's acrylic a plastic not a precious metal.
