type of algae ??

[Mstanker]

well came home to this stuff on my rocks, is that like good for the snails and inverts?

 

[fishroomlady]

I'm not sure what you are asking about, the light green??

 

[Mstanker]

ya sorry, the green stuff on the rocks.

 

[fishroomlady]

I think it may be the beginning of coralline but I could be wrong on that. It's certainly not a type to be concerned about and your inverts may consume it....

 

[Mstanker]

seem really weird to have yellow algae on my rocks now, over night. Think i should go 12hrs no light?

+1 to the beginning of coraline. If you look closely, you can see it changes from green to purple/pink all throughout the rock

 

[Mstanker]

So would everyone say that this is a good thing happening?

 

[prsnlty]

Yes

 

[NanaReefer]

Regular green film algae.

 

[Mstanker]

So this is what the algae looks like after one week is up tomorrow. Should there be some kind of action taken?

 

[NanaReefer]

Not really. Turbo Snail maybe

That's a normal part of the rock cycle. Different algaes will grow initially and periodically be taken over by another. Eventually the dominant algae will be a calcareous type called coralline algae. Can be shades of greens, purples, reds, and yellow. Your tank will go through much more dramatic changes so don't worry, what you have on the rock now is completely normal.

Alright then. Seems good to me
