So it's 2010 now. Who still uses a calcium reactor and who's all on 2-part dosing?

Thats not much for your system Levi. With my 70g cube back in the mid '90,s I used to dose 30ml/day of 2 part. Unless it was more diluted or something.

My fear with a Calcium reactor is a pressurized cylinder around corrosive salt water, panes of glass and $1000's of dollars with of livestock (My doser is much less explosion prone... at least I hope).

I dont recall ever hearing of that, but I suppose any pressurized cylinder is a concern.

Anywho, my answer to Tony,s question is, a 2-part also and kalk. Thats all I have used since shutting down my large tanks, which did run co2 reactors. I still use Seachem 2-parts and most of Bens, 3-part additives.
