Unbeatable Algae lol

[FishFrik]

I have this weird kind of algae growing on the back of my tank, LR and some part of the front of my tank that can't be eaten by my snails. I can't even scrap them off with my nail lol. What is this? Early form of coralline?

Sounds like coralline.

how about a pic and what color

 

[FishFrik]

It's green. Some circular spots are brighter

A pic would help us give you a more definitive answer but the description sounds like coralline.

I'll try to take one tomorrow. I hope it's coralline XD
