Question for Kalk users
 

How do you guys run your reactors in regards to refiling with powder. Do you let it run right out before adding more, or add a little weekly or so regardless of the level in the reactor? Do you dump out the contents regularly and start fresh or just add new on top of old?

I add some every 2 weeks (which is where there starts to be very little undissolved at the bottom of the reactor), and I usually add 2 TBSP at a time... This is for my size and evap rate.

Since KALK will only get soooo saturated, it's not too bad to have too much in there (naturally to the point where you have toooooo much in the reactor that undissolved bits start flowing into the tank, which is clearly not good :D )
