UV Sterilizers

[Kruss7]

Hi guys, looking to install a UV on my 80g display (20g sump)

Looking to eliminate dinos (Ostreopsis)

Was wondering what brands are recommended? There is a clear large price difference between brands. Is it worth the difference in price? Positive and negatives?

I use a Pentair 40 on my 75g as it is intended to control Ich and most smaller units are incapable of that.
