9 watt coralife worth using? Please help lol

[Mainereefer11]

I have a 9 watt coralife uv that I got for a steal bnib. I have 55 gal water capacity. Is it worth unboxing it an using it even if I tune it back to like 100gph? I have a water manifold so I don’t need anything else. Plug an play almost. Will it be beneficial or a waste of electricity.

Use it. I use one on my 40. Don’t mess with the pump. They typically are matched up with the proper flow rate. I guess you could slow it even more if you’d like.
