YWG breathing fast and looking unwell

Is there any downside to using one? I have some money to dump in the tank and that seems to be a good option.
Change light bulb once a year. For my UV it’s 20$ for a new light. It’s built specifically for my tank.

What’s cool about Uv is it kills unwanted algae in the water column. Negative about them is they kill coppeopods.

I would look into it, I do want pods and a refugium, but maybe I would only run it sometimes to keep the pods alive.
