problem maintaining proper parameters

[Aquattro]

whether or not kalk will do it will depend a lot on evaporation rates. I went thru 5g per day, so that much kalk was more than enough. As with anything in this hobby, YMMV. If you're evaporating 1/2g per day in a heavily stocked tank, it may not. You can figure it out mathematically by detemining what your consumption rate is over 24 hours, then determine the amount of saturated kalk you'd have to drip in the same time period to maintain levels.
