So what is this on my sand? I'm almost 100% certain it is bryopsis but looking for second opinions. I battled bryopsis almost a year ago, didn't look quite like this, but with Tech M, and keeping Mag over 1600, it hasn't come back, until this. Probably 2-3 weeks ago, my mag dropped to 1200 (I forgot to dose) and bam, this happens, my sandbed looks like a lawn.

I just got mag up to 1500+ yesterday and maintaining it there, so hoping in a week or two it goes away. A lot of it has already started darkening, so hoping that's a good sign.

Anyone?
