calcium dispenser, when to refill?

[crob500]

Just a quick question,
I am running the calcium dispenser off of the osmolotar and am very happy so far. Its been a week now and I believe I should be thinking about refilling the dispenser, so my question is, if there is any Kalk particulate left in the bottom do I need to refill the container? Thanks,

C

Even with the reactor you did get a precipitate as the RO water will contain some CO2. In general for every 7gals of RO water used in top off 2-4 teaspoons of kalk should be added. Every 3 months you should remove and clean the dispenser with some vinegar and remove the precipitate.
