If you have the room for a reservoir i recommend forgoing the kalk reactor and just mix up a few weeks of kalk at a time. I have a 55 gallon drum in a closet on my 180 and a 37 gallon one for my 90 and they each last a good while. I have used kalk reactors in the past but had difficulties during operation , plus they are expensive.
agreed, its a lot easier that way, you can use it in your top off, make a bunch at a time, and save a bunch of money by not buying a kalk reactor. i have used a kalk ATO for all top off for quite a while now with no probs. just remember with dosing kalk mag. levels drop after a while. HTH
