Using the K-2006

You are doing great! TA at 100 is fine. Your CH is high but as long as your water is not cloudy, you're ok. Just don't use any cal-hypo and don't let your TA get high. BTW - The only way to lower CH is to do a partial drain.)

Thanks again Watermom – a partial drain, hmm. I have hard water here in Louisville.
From the water company - Pure Tap®, Louisville Water Company’s tap water, is moderately hard, at 159 mg/L or 9.3 grains of calcium carbonate per gallon.
So would a partial refill actually help lower my CH level?
