I just noticed this patch of odd algae or sponge. Its dark green in color but feels spongey. Ive never seen it before.
I think its macroalgae search codium
So it's been about 4 months and this is what it's turned into. The only other piece of it that I can find is right next to it in the upper left of the mass. It's now the size of baseball (A tiny bit bigger). If you guys are right about the ID, it grows extremely slow. Think I could transfer this to the sump? The ball is only connected one little spot and can be easily removed.
