How does the Tunze calcium dispenser work?

I know it's a container you strap to the side of your ATO bucket. Does it work with the Tunze storage container?

I think you fill it with KW but how does the metering pump mix it. How is this better than setups with kalk reactors/stirrers?

The calcium dispenser has a clip on the side that lets you clip it onto the Tunze storage container or any other bucket or something similar. The metering pump mixes the kalk powder when it pushes water into the bottom of the container. I wouldn't say it is better than a kalk stirrer/reactor, but in most cases it is sufficient and provides a simpler, cheaper solution.

What size range of tanks is the recommended for and is it safe from overdose?
