Does a UV sterilizer help with coral toxins?

Does a UV sterilizer help break down/remove coral toxins? Particularly zoa or paly toxin.

Long story short, my corals have been looking upset these past few months after some new frags of assorted zoas and softies were added, and water parameters are always testing stable and in acceptable ranges, so I'm wondering if some coral is releasing toxins that is affecting the others. I'd like to buy a UV sterilizer like the light I attached to this post. I have a Fluval Evo 13.5, so the bulb would be in the back chambers away from fish and coral.

I know UV will help kill bacteria and algaes, but can mess with phytoplankton food chains, yet what about coral toxins? Would this be worth the purchase?

Carbon filter is a safer option, imo? UV might degrade some molecules but what if the new molecules are more toxic?

Carbon would just bind it to keep it from bouncing around and impacting things. Carbon is the common solution, UV does not fit the application, as far as I know?

Let us see what the other folks think/ know about the situation?

Well, the thing in your picture is the wrong kind of uv serilizer, for starters. That's a UV light.

But carbon is what you want.
