Lime water question


New member
How often do you add limewater (pickling lime) to you tank? Can you make an ATO water reservoir that is filled with limewater and add it everyday. Also how much can you add in a day?

My 30 gallon freshwater reservoir gets 2 cups of kalk powder (saturated) and lasts a week - 10 days. (3 - 3.5 gallons a day) If you are not in need of that much, you can make a less saturated mix. If it can't keep up with the need, you can add a little vinegar to increase saturation or dose two-part in addition.

The kalk meets my calcium demands, but I have to buffer alk with baking soda.
