Has anyone tried using a mixture of Calcium Hydroxide with Sodium Hydroxide to kill Aptasia? I just got some Sodium Hydroxide today. I know that the mixture will kill anything it touches. I tried just the lye(Sodium Hydroxide) alone today but it doesn't mix into a paste like it needs to thus the need for Calcium Hydroxide. The little bit I tried killed Aptasia so that it was unable to react and release seeds or whatever they're called.
