You could, but I still think it's not the greatest idea. The reason is you're trying to tune it to reduce nitrate (and the fact that it adds some Ca/Alk is just a happy bonus), not trying to tune it to maintain Ca/Alk levels in the tank. Ie., Ca and Alk will get used up at rate "X", NO3 will be added at rate "Y", you want to tune your sulfur reactor to match "Y" and you're stuck with whatever Ca+Alk rate that it produces. If that's less than "X" then it's not going to maintain the tanks Ca and Alk. Whereas the Calcium reactor is directly tunable to the Ca and Alk.
