Supposedly - I am sure I can find the workign formula for it. I used to drip add it to keep PH and calcium up. In a large Ca hungry stony tank I know some people have added Kalkreactors to supplement but they really cannot maintain Ca/Alk like a good Ca Reactor without some other kind of supplement like JimN mentioned (2 part like BIonic etc).

I too have a JimD special and have it inline with the topoff from my osmolator so it pushes top off water from the ro/di resevoir through the kalk reactor to top off with a moderately saturated kalkwasser solution. This works real well for me since the osmolator is so darn accurate but I have heard horror stories of conventional float switch kalk topoffs getting stuck and nuking the tank from overdose.

The Korallin reactor I have is going in this week (had to DIY a gasket - apparently the proper size o ring was not available) to work in conjunction with the Kalk unit - I also got a controller so hoping I can keep my PH steady as well as ca / alk levels.
