I haven't purchased one yet, but I'm leaning towards the Korallin reactor myself. As far as clams go, I have 2 and several hard corals. So far I have had great success with the calcium drip.

should i get a calcium reactor once i get three more clams, or should i drip kalk
If the only calcium consuming critters in the tank are the 3 clams then you should be ok with kalk. If you have corals along with clams then I'd get a reactor.

The Ca reactor will almost be a must, both would be great.
