I've found several colonies of this white creature in my system. The best description I can give is sponge- or tunicate-like.

Clusters of little tube like things with openings at the ends. They're also translucent.

Here's a couple pics:

I'm voting for a small sponge too Harmless filterfeeders. If they get to be very numerous keep an eye out.... they may foul your water if they crash all of a sudden.
