    Hi there. I have white fuzzy growths on my glass and live rock. Anyone able to identify them? There are lots of them in my display, overflow and sump. They are all small except the one on the live rock, it's about an inch to an inch and a quarter long. Thanks.

    From your pictures, it looks like a sponge. To be more specific, a Scypha sponge. These are also commonly called pineapple sponges or q-tip sponges. These filter feeds are harmless for the most part and are usually found in the sump, overflow, and attached to a variety of surfaces (rock, glass, etc.).
