Green Coralline?

[NH_Reefer]

Hi All,

My tank is about a month old and has been progressing great with minimal issues. Diatoms came and went within a week about 10 days after startup. This bright green algae is starting to coat all the rock, only where the light touches though. It doesn’t come off with a toothbrush, is this the start of coralline? I did add two bottles of coralline cultures after the nitrate cycle was complete.
Thanks!

Not coralline but the beginning of green algae blooms

hehe...lets just say its coralline, its going to be there for a little while, and you might as well enjoy it. ;-)

I don’t really mind it, it’s not particularly ugly and I like that it encrusts. I’ve just read a few things saying coralline can start bright green like this and then slowly transition to purple or pink

Not true. Coralline starts in the color it’s gonna be lol

There is green coralline, and most of my tanks get a little bit of it before the purple starts kicking in. Not sure if it’s the coralline changing color, or the purple just overgrows the green.

That being said, yours is much darker green than what I’ve experienced. It’s hard to tell from the photos, but is it actually a hard encrusting algae, or do any parts of it have some sort of filamentous look to it? You say it doesn’t come off, so it may be a shade of coralline, just an oddly dark green. I usually see a very light line green.

About a week ago there were a few small filaments that I only say because they were catching bubbles but those disappeared quickly. It’s all just encrusting green now, doesn’t budge at all with a toothbrush.

It's natural. All tanks have it although Im not sure why there isnt a name for it. Well im sure there is but i havent heard it browsing the forums here. It will eventually go away as other algaes out compete it.
