Kalk Reactor Vs Calcium reactor

[vanreefer]

I ran my tank for a while maintaining ca and alk (low end of scale) with kalk that I would mix then drip... what a PITA.. I switched to a ca reactor, which pretty much takes care of itself... growth following the ca reactors introduction is explosive I have mostly sps but the softies are growing well too.... I have enever used a Kalk reactor.... or know there expense... but if you were going to buy something, I would go with the ca reactor
