Hi All - Any idea what this is growing under the GSP? It’s a light hue of neon green (less neon than the GSP). Have A few patches of this throughout the tank and nothing seems to want to eat it (urchin, hermits, snails)

Can’t tell with this lighting. Would you post pictures under white light?

@Dan_P Good call - How’s this look?

Are you referring to the pink stuff? That’s coralline algae and a great sign it means your tank is maturing and stable.

It is clatharina sponge which is a poriferan type sponge and can grow consistently and smother rock and coral. Your best bet to is to pull the rock and place it in a container of tank water and use either a dental pick or small crochet needle and pull it off and discard.
Other option is to inject vinegar into it with a syringe but most effective is the manual removal.

The coralline is great (and was long awaited, tank hit the 2 year mark).
Trying to figure out what the green growth under the GSP and a few other areas in the tank is. It’s light green and has started growing almost tubular

Looks like a sponge.

Oh I see now and vetteguy is correct!
