What lays eggs that look like tiny pineapples?

[AnnetteG]

I have all these tiny pineapple shaped somethings all over the inside of the sump and refugium. I think they must be eggs because they're all the same shape and are just on the glass and some are stuck on the sides of the pump, some on the blue sponge, but there aren't really any that I've noticed in the main tank.

Any guesses? Sorry no pics, but my camera won't do pictures of things this small. They are creamy white and pineapple shaped even to having a little tuft of something coming out of the end not stuck to the glass.

Thanks!

You're right, that's totally what it looks like! I didn't expect them to spread all over the glass, but I'm sure it came in from TBS. Are they good for anything?

They are just harlmess filter feeders that will come and go depending on nutrient levels...
