Actualy it might be the worst way salt mixes are almost all low for Mg content. I have tested two popular types now and while they are not overly low they are under 1100 in a fresh mix.

there was a big thing on this a couple years back and it has to do with the cost of the Mg additive and how much is needed.

Johnny Reefer, how are you calculating that you have that much water? like I mentioned befor you have to take off the amount of rock/sane/ect you have or you will be buying way more Mg additive than you will need. I have a 170 gal setup with the tanks, but when I did my calculations on how much Mg attitive I used to how many PPM it went up in my tank it worked out that I only have 95.2 gal of actual water in the system. this is a nice thing to do if for no other reason than to figure out exactly how much water you have for future additions of different attitives. takes the guess work out of the picture.
