I've got a group of purple death zoanthids that I don't want. They aren't on a fragable section so I need to kill them off. I tried hitting them with aiptasia x with the flow off but that just pissed them off for a week and they are back to growing again. I feel like I've heard of people using putty to cover them up and wanted to double check before I cover them up in waterweld.
Thanks for any input.
