So I had a little battle with dinos and wiped them out by stabilizing my nutrients and running a UV sterilizer. Now I got some uglies (which I know is desirable with the fight against dinos). This algae is green, fast spreading, and does not scrub off with a toothbrush. It appears to be a hard algae but can it be coraline? What do you guys think it is?
