almost neon green spots all over the back glass New Coralline?

I think that I have new coralline growing everywhere all over the back of my tank. I have almost neon green spots very thiny growing and then for sometime a encrusted crimson red algae that i cant brush off my live rock. Ill try to take some pictures.


Here is the rock that its on



There is a picture of the crimson looking algae cant get it off the rocks?

 

does the "neon" come off easily are is it hard like coraline? if it is hard then yes new coraline growth but if its slippery and comes off easily i wanna say film algae, which my snails love.

 

No its hard and doesnt come off

 

then im going to go with answer choice #1 coraline. LOL

yeah its good kinda circular and sporaticly appeared around your tank right?

 

yes it has and every where i like the neon green.

 

If it fizzles in vinegar, then there is or was probably coralline. Not necessarily coraline though, sometimes coralline dies and gets covered in green algae. There are some hard non-calcerous green algae also. Most likely though, it will begin to turn purple as your tank matures more. Regardless, this is a pretty common sign that your tank is maturing and coralline is about to start taking over. If it stays green without purple/pink coraline showing up, you may have high silicates, as there is some theory floating around silicates can discolor coralline and turn it greenish. Or could be green coraline, although some say this is actually fairly rare.

 

Nice thank you for the info, any info on the crimson red algae?
