Advantage of high Mag?

[hkgar]

NSW is, I believe about 1320.

I read of some who claim good results with Mag of about 1500. Are there demonstrable better results with higher mag. If so what are the benefits?

It aids in running Higher alk and cal lvl without precipitating . I raised my mag to 1600 when combating algae blooms when my system was young.
