It's hard to say, given most references don't ever go into it, but 1500 ppm won't be a problem.

Some people push it to 1700-1800 in order to get rid of certian kinds of algae. 1500 isn't an aiiue.

Agree,I've had mine up past 1550 ppm with no issues.

*It's been mentioned a few times that elevated MG can help combat Bryopsis.

Oceanic salt mix has very high mag levels.

Per Billy's tests it has a mag level around 1650 ppm at a salinity of 1.0264. Hobbyists use this mix without problems.

I was also wondering about high mag. I use instant ocean and my Elos kit read 1650. I guest this is ok?

That seems odd since IO is only "rated" at 1300 Mg.
