Kalkwasser Stirer / Reactor

Kalkwasser Reactors & Stirrers

Kalkwasser reactors have been designed in a couple of different ways; there are some which utilize a powerhead to mix the solution, some that utilize a motorized stirring rod known as a "Kalkwasser Stirrer", or ones using a magnetic mixer. In the diagram above, the Ice Cap Magnetic Stirrer is described. 

Each of the reactors is somewhat unique and operates a little differently but most of them will require a timer to dictate the frequency of stirring. The rate of dosing is best controlled independently of the stirring itself with a programmable dosing pump but you could technically use a powerhead on a timer or even your ATO pump to dose through a reactor.  Just reference the particular manufacturer's instructions for the plumbing, necessary equipment, and delivery options. 

HOW IT WORKS

The reactor is filled with a significant amount of kalkwasser powder which is then periodically stirred with incoming freshwater from your ATO reservoir to ensure every dose is as concentrated as possible.
