I don’t see green macro in first picture, it looks red to me. Use white light and get close. Don’t make us guess? Use proper adjectives to describe what you see. This is my wild as guess.

Gelidium, Red Wiry Turf Algae​

Many species of short creeping red algae exist so the hobby generally lumps all of them under the heading "Gelidium", (the genus that is home to many of those species), and the common name Red Turf Algae, or Red Wiry Algae.

Manual Removal: Difficult. Macros that have fragile runners and creep along the rock are the hardest to manually remove. Do the best you can. Use a dental pick to remove it if possible. Fragments of the algae can spread though, so make sure to net any pieces that break loose. Yeah I know, it is boring as can be, but if you do it once surgically with a dental pick the problem goes away for good. If you can take the rock out, all the better.

Clean Up Crew: Emerald Crabs, urchins, sea hares, and large turbos
