ID What the heck are these???

I cant tell what these are. The green stuff is hard and is everywhere and the other things I cant get off with a sponge....

How long has your tank been up and running? The first pic seems like green coralline algae, which is a calcium-based for of algae, so it’s much more difficult to remove. There are other species that are pink and purple as well. Does it grow in circles?

Can’t tell what the second pic it though. Need a better pic.

The tank has been running for well over two years now. The green stuff grows in the shape of like a mushroom and the other pic is white squiggles on the tank walls.

Anyone got an idea of how to get rid of this stuff

I really cannot tell much from your pictures. White squiggly things are probably small tube worms. A single edge razor blade will get them off easily (plastic blade if tank is acrylic). Not sure what the green smudge is.
