I have a large rock of gsp as u can see in the front. Would it be a problem for it to grow on the main rocks and grow around my corals like my hammer and etc.
Forgot to say it’s alrdy kinda started growing on the main rock might try scrapping it off next time I’m in tank. And move the gsp away from main rocks a little. Love the gsp tho always flowing so peaceful

In a perfect world - no, but GSP will overgrow everything in its path. You'll have to trim it back occasionally to get it to grow around your other corals.
