Coralline thats flo-green?

[Creetin]

AFter adding the buffer, calcium and magnesium i noticed some growth in the coralline but also noticeably there were some areas which are green or even bright green like those kinda green mushroom color. Is that CA? Best thing is, i dun even have this color/species of CA thats green in the first place.

Yes, coralline algae comes in green too.

I dun suppose its algae right? hopefully its CA, since its encrusting my LR.....

[Stenopus Hispidus]

Green CA is hard and it can encrust glass as well as LR. May be quite unsightly when growing on LR. Got to really get a blade and scrape them off the glass or brush them off your LR with a hard brush if you really mind otherwise I don't see it creating too much of a trouble.

I think the greenish CA is pretty cool, I wouldnt get them out unless its bad algae... hopefully more purple ones will come along

[Stenopus Hispidus]

For me, I scrape them off because they are growing where they shouldn't otherwise I will leave them alone as I do not find them detrimental in any way.

If you don't mind keeping Green CA, then that's no problem. Anyway, the presence of green CA can inhibit nuisance algae from taking a foothold on them to some extent...so they are quite functional in that sense as they actively reduce nuisance algae's real estate
