Are you using other Zeovit products? Someone correct me if I'm wrong, but I believe Spur2 is a pretty touchy additive and is only recommended in well-established Zeo tanks. I'm sure the health of your corals will return, but you may want to bring up this issue on the Zeovit forum to see if there's anything else you should do.
