You said not to use the other one for kalk top off.I still haven't had an incident yet.I did however place a float valve for that one.This one here works fine.I ran it for 2 years without any problems.I never had this model overdose on me once.Plus it goes on every few hours or so for 30 seconds.I will play around with it in a few days once I see what my levels are at.Jnarowe I think you are a little to paranoid.
