UV Sterilizer Filter

[Stingro]

Is it really worth it? It doesn’t seem to offer much unless you have really bad algae problems.

Thoughts on which UV Filter are best and how useful?

I use a TurboTwist 36W custom plumbed in-line on one of my FX6 filters on my 300. The flow rate is too high for killing any bad stuff but works great keeping water clear and getting rid of free floating algae that can cause green water. This is what a lot of pond UV's are basically set up for.
