There are about 8 ways to specify alk, mEq/l, dKh and ppm of CaCO3 are all valid. 9.6 will be dKh, as 9.6 mEq/l would likely kill everything.

Good link Brad. As a newbie I confused the conversions and tried to raise my Alk up to 8 or 9 meq/L. It did kill almost everything, but my snails were the first to go.

thanks for that link Brad.. haha, I use the hagen alkalinity test kit and it measures in mg/L .. so it doesn't help me as it's not the common measurement... nice to have a handy little converter.

Sorry about that. Next time I should clarify. My 9.6 was a DKH value which converts to 3.43 meq/l

All from a salifert kit.
