Bizarre, I use IO and don't think I've ever had a Ca problem .... oh well, I guess everyone's experiences are always a little bit different!
Oh and .. I can't add much to the already significant amount of info in this thread, but I do want to mention that the conversion from alkalinity units meq/L to dKH is 2.8. So 4.0 meq/l is 4.0*2.8=11.2 dKH. I apologize if this info is already up there somewhere.
