I am sort of with you on this theory. Most of the time I just go by feel and observe the condition of the corals and tank first and if they seem to be growing and maintaining good health then I wouldn't bother testing. In my case, growth has been stunt the last couple months so therefor I did some tests. In doing so, I found that both my Ca and Alk are well below normal with no apparent changes to the Calcium reactor production (media disolving rate is normal). This lead me to believe that my Magnesium is not up to par. Like many people, I've never encounter this problem before until now so hopefully adjusting the magnesium level will re-stablize things again.
