Should I use my 56 zoa colonies as food?

The other option you could do is dry out the rock kill it all that way and then reseeding the rock with clean live rock later.

But shutting down and restarting isnt the best :/

a fish that eat Them is good but once the fish is removed or dies j hear they come back pretty quick

I have a great filefish in my tank that took care of all my pest anemones etc, however, that being said, the only coral he did eat was Zoa!!!
