Can NA grow over Coralline?

[HawkeyeDJ]

After a year and a half I'm finally starting to see coralline algae growth. Ever since I put a live rock in the tank, I've been battling NA.

Will the NA kill the coralline like it has several of my corals?

By NA do you mean nuisance Algae? If so, yes algae will grow on any hard surface it can find.

Maybe but it will have a harder time on coraline, you need snails to help you keep it clean

Generally other algae can not grow on top of healthy coralline algae. It's one of the benefits of it. However if left to get out of control in the spots without coralline it can shade and kill/encroach on the coralline areas

Yes. I should have made that clear before abbreviating. So nuisance algae can kill off my coralline. Thanks.

It's uncommon for other algaes to grow on or over Coraline, but I suppose anything is possible.

I let my bare bottom frag tank bottom completely encrust with Coraline specifically to stop other algaes from growing there. Same on frag racks.
