Using really weak/diluted kalkwasser for ATO?

[fellbeast]

Never heard that before... I can't possibly imagine how some kalk would mix with some parts of water better than other parts of the same water. Leaving the kalkwasser to sit was just so that the sediment could settle out.

 

I agree.. actually with ro/di it mixes with little effort imo. Letting it sit for a few hours, all the sediment goes to the bottom. Like I said I don't put the tube at the bottom of the container, nor do I use the bottom 2 inches of the soulion in the bottle.
