It should be that it does a better job of supplying Ca than it does Alk, and in a high usage tank it won't keep up as it is only added by make up water. but in the same turn, if you have a tank that the alk is stable but the Ca drops then it works.

the biggest advantage to the Ca reactor is that it buffers the Alk way better and can maintains it slightly elivated compared to Ca.

I used to run my alk at 12dkh as I found once I got above 11 my colors just popped. when I took my Ca reactor off line for a redesigning, my Kalk reactor couldn't keep up on its own with 7 gals per day of make up water in a 120 gal system. This was a high consumption tank with extreamly fast SPS growth.

now having said all this, in one tank it might work perfectly, where the other it may not, every tank is different, and what works for one won't nessasarly work for another.
