Something very strange going on here

Has anyone seen anything like this. I have hundreds of these little white pods all over the rock and power heads. I have never seen anything like this.

Scypha sponges

What do I do to get rid of them. They are everywhere. I've had my tank over 2 years and never had them.

They are generally part of the "lifecycle" of a tank, they tend to "pop up" or bloom, as the tank is maturing. They are harmless filter feeders, whose numerous presence points to an "excess" of nutrients in the tanks. Up the water changes and they should start slowly reducing in numbers. Perhaps never 'fully' disappearing.
