I think Mg was depleted by DSBs. I needed to add it from day 1 when I had my DSB. when I got rid of my sand I only needed it to bring my water changes up to normal levels, which didn't take much with my IO. I was testing between 11 and 1200 in the IO so I would bring it up to 1350.
now I also found that when I hooked up my ca reactor with ARM media I didn't need as much also.
what I also found is that some people could use it with out even knowing. if you are pounding a Ca reactor to your tank and adding kalk through make up you could be masking the Mg condition. I could maintain my Ca that way with my old tank but I found that when I brought up the Mg I had to dial back my Ca reactor or my Ca would get to high.
I blame it on DSBs
