Tons of Pineapple Sponges

[Eb0la11]

Just wondering if having an abundance of these things is a problem ever? Particularly all over my sump glass and refugium?

overfeeding will allow these sponges to proliferate
They are good, are taking nutrients out of the water column

I have them here and there in my DT and expect that they will grow well in my new sump. They feed on fine particles and bacteria in the water column and are generally a sign of good water quality. EDIT: Scypha spp.

sponges = good i have tons of these guys in my suymp and they just take fine particles out of the water and absorb nutrients

Ok sweet, no worries then! Thanks guys. I dont have as many in my DT but perhaps one of my fish or inverts likes to eat them or something up there.
