I wouldn't dose anything that says "purple up" or "coralline stimulator" because these additives usually don't do anything for corals and parameters tend to easily go out of whack if you don't does right. I would go with a two part additive. I use Oceans Blend. I don't know if you have heard of it or not but its very good and I get a ton of coralline growth.
