Todd,
The problem with just using a Kalk reactor is that if you have good water evep your pH could get high. Oh the other hand, if you use just a Ca reactor your pH could go low.

I've found a kalk reactor will not raise Ca and Alk levels in a well stocked tank, a Ca reactor will.

If I had a well stocked tank and had a choice of only one it would be a Ca reactor.

FWIW, I have always used both.

Okay thanks i kinda figure that be what i hear tryin to keep things as low cost as possible

I use both on my tank. Ca reactor would be my first choice if I could only have 1
