Could someone please tell me what these are.

Hmm, some type of colonial ascidian (tunicate) perhaps?

Actually it a type of bubble algae.

Botryocladia skottsbergii I believe.

I have something like that growing in my sump also.

Mine doesn't have the dots though.

^^Basically Red Valonia, a red version of bubble algae.
