Green Coralline or something else?

[Reaper_Six_Four]

Hey everyone,

I just noticed a really thin film growing on my rock. Was wondering if this is the beginning of green coralline or something else.

Not sure if the pictures does it any justice.

i haven’t tried to remove any of it yet

TIA

Green film algea on some new rocks. A good sign so far

Doesn't look like coraline. Looks like algae, and brand new rock. See green and brown algae growth

It’s green algae alright, not so much of the coralline type

Is there such a thing as green coralline algae? I have pink, purple and dark red....

Yes green and yellow but very rare in the hobby.

You’d see little bits of lots of colors on old ocean live rock, like green shades, reds and whites along with the purple and pink we are more familiar with.

Since the embargo on real rock don’t seem to see those colors much anymore sadly. Certainly not grown from scratch in home systems

Anything I should be concerned with? If so, what should I look out for?

No perfectly normal algae growth. Id be more concerned if you didn’t see it…

if it starts to get really dark and all over, could be a sign of high nutrients and might want to increase water changes and reduce lighting/feeding. But from the picture I wouldn’t say your at anything but a normal level.

this is the start of ‘ugly phase’ that just comes from using dry rock

Yes but most we see is purples and reds. But there's many different colors.

Yeah, I have been feeding somewhat heavily. I’ll pull back a bit.

Thanks for the info

If it starts getting heavier consider a turbo/margarita snail or two. They can mow down the algae, but then it’s hard to keep them from starving once it’s gone

Buy a clean Up crew if you haven't allready

My coraline algae started out neon green. Can you blow it off the rocks? Is it hard like coraline? If so, it *could* be the beginning of coraline algae taking hold.

I have a CUC with turbos. They do a good job so this caught my attention.

Haven’t tried yet.
I was doing my “good night tank” round that I do every night before bed with a white light when I saw it.

That rock looks like you just set the system up.
I hope you had a long cycle? You have multiple coral frags including sps in there. Stay on top of all your parameters and keep your fingers crossed,
Going through the ugly stages ( getting bacteria strains fully established) can be very stressful on corals

It’s been cycled and ran a period of significant brown algae before my CUC cleaned up. Those Candies and GSP have been in over a month

Tried brushing it off today with my water change but didn’t come off.

I certainly hope it is coralline but doubt it.

Update on some more observations. If anything, the blue legged hermit crab was the seeder. Just starting to see more red spots as well.
