    I two larger and a few small (not visible in the picture) of these round, light blue, puffy balls on my LR. They came with the LR and have since grown a little bit. Is it a kund of a sponge? What is it?

    Welcome to 3reef and they look like sponges to me. They are safe to keep.

    definitely blue ball sponges, i have a few in my tank, most of them are yellow. they do a decent job at filtering the water, take a toothbrush and scrub em every now and then
