After months of scrubbing and pulling bryopsis off my live rock, I began trying the elevated Mg trick......and low and behold, it seems to be working.

I know some members have tried it without success, and I was wondering if y'all were using Kent Tech M or another brand? I was using ESV without luck, but read on RC that the Mg sulfate seems to be key ingredient. So I switched to Tech M and have seen some positive results.
