Aquarium Systems make a CaCl additive intended for reef tanks called Reef
Evolution, but it looks like just straight CaCl (I didn't realize CaCl was
okay for a freshwater tank, otherwise I'd have tried some myself!). It's
about $12.00 for a 16oz bottle (catalog #ECC-16). They also have a
Calcium Hydroxide additive. I don't know if that's okay for freshwater or
not.

I highly recommend the LaMotte hardness kits, by the way (they are fairly
inexpensive compared to some of the other LaMotte kits too). I picked up
a used calcium test kit at an LFS clearance sale for $5.00, and I love it.
After using their Direct Reading Titrator, I never want to go back to the
old add a drop-put cap on tube-shake tube-remove cap-add another drop-put
cap back on-etc. method of titration again! I know they have a kit that
tests calcium, magnesium, and total hardness, but I haven't been able to
find it anywhere, except as part of a very expensive master test kit.
