i have this reddish maroon algae growing in my refugium. Can anyone tell me what it is. It has grown slowly and my chaeto has shrunk to pretty much nothing over the last few weeks. I thought it was cyano but it's not on the rock it's in the bare bottom and spreading up. Not sure of my phosphate level. Hannah checker coming any day now. Temp 77 Nitrates are between 5-10 ph 8 alkalinity 11 calcium 420 salt 1.026.
