Catherine those are rather ideal looking numbers. Man I wish I knew what I could adjust to make mine similar...
I wonder if it's a case of too much calcium reactor / not enough kalk? I have the drip rate set on the kalk reactor so that it doesn't exceed evaporation. If I set the pump to 10% or higher of its rated capacity it will overtake evaporation (luckily it's a very slow trend and easy to spot after a day or so, so it's not like I'm in danger of overflowing the sump unless I get VERY inobservant..).
At my old place when I ran both I had the kalk run directly into my float valve. I switched to a metering pump so that I wouldn't have to worry about the valve clogging anymore.
Ok here's my next question, for those with kalk reactors, how often and for how long are you running your mixing pump?
