Can someone identify this thing. I have lots of them growing in my sump, they seem to be only growing in the bulkheads where there is very little light.

I think they're a type of sponge(Maybe) called a tunicate. (The spelling might be wrong.)

They're harmless and usualy grow in high flow areas. :smile:

high flow areas you say?

like the baffles in my sump?

thanks :mrgreen:

Probably a sponge like this.
