White spots on tank Glass

[smeac72]

I have these white spots on my glass they seem to be multiplying rapidly. What are they and how do i get rid of them?

It could be a few things. Need a pic to really identify it.
It could be hydroids which are like mini jellyfish
It could be copepods that are moving around everywhere
It could be fan worm tubes if they are hard and calcareous
A pic would be best for identification, or maybe even a really good description...

We have had a hydroid bloom going on for a couple weeks now as well. It is fading now. Just brush them off the glass, your fish will eat themn.

Take a look at this pictorial hitchhiker guide and try to match what you see in the photos for an ID and a bit of info on the critter:

What you're seeing are likely "pods" of some type.
