Unknown Algae

This looks like sea lettuce and is starting to overtake the rock in areas -

Anyone have any idea what this might be - it is becoming a pain - it has even covered the shells of the snails and hermits

Any help would be greatly appreciated

Rip it out ? It is rooted pretty well in the rock - i would have to pull it out which i could do - any other thoughts before that route ?

I mean, if it's overtaking your tank and not desirable...

Turn off your pumps and squirt some h2o2 on it then let it set for a while.
Do a section at a time over multiple days. I’ve been spot treating some GHA doing it this way and haven’t had any trouble.
