    Hello!

    This question is directed to those who dose Kalk and don't just put it in the Top Off water. I am curious as to how much you dose a day? ( know david grigor does this and i am curious as to how much you go through a day,

    29g tank lasts anywhere between around 10-14 days give or take ( I don't keep to close of track ). I dose based on alk levels not evaporation. I have a secondary gravity feed topoff if evap more than daily kalkwasser additions but that is not very often. If/When alk gets below 7dkh ( mostly becuase of pH fluctautions impact coral consumption of alk ), I will add a kalk slurry ( 1 teaspoon ) in a couple of cups of water vs. adding any carbonate/bi-carbonate additives. Reason is calcium levels would get out of what and really avoid calcium chloride since I rarely do water changes I avoid as much chloride additions as possible.
