What do I have now?

This is a new type of algae that I have never noticed before. It’s in a few spots around the tank and isn’t spreading super fast. Last test was done on 2/6, nitrates were 20 and phosphate
was .05.

hey that so far looks like a rare rare blue green expression of monerans...cyanobacteria

in marine its red, usually. so far, that's a planted tank-type cyano mat/called so far. can you get clearer picture, some of it pulled out into a white bowl or something

 

[ryewalk84]

I was thinking cyano but have never read anything about it being his color. I sucked it off the rocks today after posting. Can post more pictures when it comes back. Does it act just like the normal red cyano?

Yes it's very similar, that could have been some garden soil monerans that rode in last time the wind blew, never know. Patchy invasions occur often on a real reef, it's no indicator of bad water or param reactions

Siphon guide it out as needed in my opinion just like the red, no meds, you've acted early.
