This tank is a 20g nuvo that I started with all dry rock. The tank is a year old and I have noted that this algae showed up about 2-3 months in and in the sandbed. It just disappeared after a while and never really took off. I've recently changed up the tank to be an SPS tank so the lights and flow have been cranked up and the algae reappeared. It looks like it could be bryopsis but at the same time I don't think its looks quite ferny enough. So I'm not sure. I've had GHA in my other tank but that algae looked more slimy than firm. Any ideas on what it is and how to combat it?
Nitrate 0.6 ppm
Phosphate .07 ppm
My nutrients have been pretty stable for the past 2 months since I made the change.
Phosphate I've between 0.03 - .1 ppm
Nitrates seem to fluctuate between 0.2 - 8 ppm
