MArc,

Instead of having the water taken fom a storage resevoir I am doing the same thing that my CA reactor does and takes water from the sump to use in the Kalk Stirrer.

once I get to Van I will get a good storage container to keep topped off with water for top off and dosing. but for now I am curious. and lazy. [img]images/smiles/icon_wink.gif[/img]

Titus,

I add the Kalk manually. The stirrer is clear on the bottom so I can keep an eye on the level of Kalk inside and replenish as needed. When I had this running on my 90 I added Kalk once a month or so. I am just too lazy to mix it nightly..
