Re-using Kalk

[Cammed_02]

I am about to start dosing kalk via my gravity fed ATO. I mixed the powder into solution and let it sit overnight.

Now from what I have read, the powder buildup on the bottom is to be left there and only the now "limewater" can be dumped into the ATO.

With regard to the powdery substance in the mxing container, do I leave it there and just refill the jug with RO water, mix, and let it sit overnight to precipitate out again and refill the ATO when needed?

Or do I discard the powdery substance and mix up a fresh batch of kalk?

Reuse it. Just add more as it gets dissolved/used up.

Yep and yep...just keep adding more water. I rinse mine maybe every few weeks.

Good to hear, so I shouldn't even have to add more kalk until I rinse the jug? The brs kalkwasser I bought is gonna last forever then huh?

Yes, it is the way to go.
