Also, just like gha, cyano, and dinos. Chances are, coraline "seed" is already in your system.
Also, not all bottles have "seed" in them. Ie, the Kent purple up is just a alk/cal booster. Other coraline kits do contain live seed, but again, they won't take off unless your tank has the appropriate growth conditions for calcification
