I took a look at your build, I wouldn't expect your tank to go through a lot of Mg, back in the days of the massive Mg crashes we used to have about 2lb per gal of rock, and cramed full of SPS, and DSB even at that point my own tank never developed Mg problems for about a year. I had a 8" DSB, 240lbs of rock in a 90 gal tank, and every inch was filled with SPS.
I noticed a while ago the trend now is more open tanks and thinner sand beds, and I also noticed people stopped posting of low Mg. Keep an eye on it but I don't suspect it will take more than the odd addition during water changes.
but then I could be wrong also
just my 2 cents
