Green Coralline Algae?

[ChameleonNYSea]

Does anyone know what this is? It looks like coralline algae to me, except it's green. Thanks

Is this type supposed to be more invasive or something? It looks less appealing than the purple (in my opinion) but also much easier to scrape off the glass.

When mine looks green if I leave it alone, it turns purple eventually.
