This plant is calcium based, and it will uptake the calcium in your system, which, of course, competes with hard corals that also need calcium. If you don't have hard corals, there's no worry. If you do, then just maintain adequate calcium levels in your system and it should be fine.
I find these are great plants, fast growers, and a great place for micro stars, worms, snails, etc. to find safety from predators.
