I have been dosing 2 part, but will start with Kalk. soon. My question is... I have an Approx. 1 1/2 gallon evaporation daily. I do not have an auto top off system, I manually fill about every 4 to 5 days. Can I drip an IV bag that is a Liter of Kalk solution per night and still fill as regular or do I need to fill everyday? Appreciate the advice.
