I got these red algae growing on the surface of my sump only in the first chamber where overflow DT water come in. I don't see it anywhere else in the refugium. grow in a clump like patterns and rough. Like to get a positive ID please.

Looks a little like Rhodophyta, aka. Red Algae. Just a guess on my part.

I recalled someone here is an expert on algae. Just can't remember who!

Looks like gracileria or a cluster of coraline algae. All good to keep in the sump.

Thanks Jan, I pretty sure it's not gracileria but "cluster coralline algae" sound satisfying
