Giant copepods or amphipods?

[CoastieFlo]

Anybody know what these white copepod looking things are? I have a ton of them that float around and appear to be dead and like to collect around my rock work and corals...about a month ago there was an explosion of them and I cleaned about a cupful of them from the back of my sump and filter floss. They don't seem to be bothering anything at all, I just assumed it was a bloom of copepods that died off or are molting if they even do that. Now I just vacuum out as many as I can when I do water changes.

These are definitly pineapple sponge and are short lived often found in shaded areas of tank or in sump and thrive off silicates and algae
