Reef rock 2.1

What is the fellings about this product? I like how it will give your tank a more established look faster and I do like the purple color without fighting the algae, have read that coralline algae can get out of control. But I don’t like that the purple is only paint over the rock which means you can’t custom cut any to fit your needs. As of right now I’m leaning towards the dry live Fuji rocks from bulk reef supplies any opinions on that? Any idea where the best place to pick up dry rock? Going in a 55gal tank if that makes a difference
