Were you dosing as a slurry or waiting until it settled ad dripped it? It you were dripping it, it shouldn't matter. Once it saturates, everything else will just settle to the bottom. Refil with water and give it a shake next time. That's how kalk reactors work. I add about a cup per month to mine. I'm just assuming that you drip, so any excess buildup on pumps mean you are dripping too much. Don't dose for a fee days and see how far your cal falls. Put that in the chemistry calc online and see what your saturated, settled, limewater dose should be.
