Deep Sand Bed

Ok here in a few days both my 125 gallon and my 75 gallon will be like 3 months old
my 75 gl, is a reef tank and i been having problems raising my calcium, probably because of low mag but im not sure cause i cant find a salifert mag test which i hear is the only one worth having
any who in the process of finding one i ran into a guy at my lfs that was telling me that i should add a deep sand bed to my refuge, so that the benifical bacteria would establish a balance and decide which levels of the sand to live at and in turn have a positive effect on my tank,
in my experience so far ive come to find that what works for 1 may not work for another, and so on and so forth.
would this or could this help my cal levels??
i wouldnt think so but in this crazy hobby anything is possible
my cal is like 300 my alk is like 11 dkh my ph is around 8.2
0 ammonia and bad stuff
thanks hope this is the right forum!!!

A deep sand bed provides an area for anaerobic bacteria to live and perform denitrification. I don't think you are going to see much in the way of a calcium increase come out of it, but it will help with nitrates if you are having any algae issues. Macroalgae and live rock can both perform the same function in a tank, so a deep sand bed isn't really a necessity.
