I have used Tech M successfully to get rid of bryopsis in my 300 gallon net system. I raised my Mag level to 2000 (tested with Salifert test kit) and left it there for two weeks with a weekly 25 gallon water change.
This is all anecdotal, but I believe the main issue to the success of Tech M in eliminating vs suppressing the bryopsis is exposure time.
If you read a lot of the threads on the different national websites, many people reporting initial success with Tech M had it come back after a period of time (few weeks), which tells me they only suppressed it, like pulling english ivy out but not getting the roots, so it grows back.
Many people that did not have success with Tech M also reported doing water changes to try to bring the mag level back down after reaching their target level.
My magnesium levels stayed at 1900+ for over three weeks straight. I did not do larger than normal water changes, and just let the mag levels fall naturally over time thru the normal chemistry of the reef tank. My bryopsis has died and has stayed gone for months now.
I believe the tank needs at least two weeks exposure at an
1800-2000 magnesium level to get the roots or holdfasts (or whatever part keeps it on the rocks) of the bryopsis.
