Kalkwasser

[rmorris2250]

Can Kalkwasser go bad? (BRS brand) I just started using it. I am currently mixing it in my ATO water, I have a 15 gal tank and no matter how light I mix it, the water never clears up. I have put a circulating pump in and still cloudy?

It can take a day or more of no stirring for insoluble particles or undissolved kalk to settle out.

You want to mix your kalk as much as possible, then let it settle for 12-24 hours. You do not want to suck up the particulate that settles to the bottom. Since you are using an ATO system as the means of dosing, I suggest having your ATO pump off the reservoir bottom so it will not pull the settled kalk.
