Really happy with my Vecton v2 400 UV sterilizer

I put a vecton 400 uv sterilizer on my 90 gallon saltwater reef tank. I also have a 30 gallon refugium / sump. My 600 gph main return pump really drops flow by the time it goes through the vecton which I put last inline just before entering the display tank. WOW! What a difference on the micro algae in the water! I didn't have too big of an issue as my water was clear before but I would get a film on the glass each day that I would have to clean. I could go two days without cleaning and in day three you could see it and snail trails. 

Now since installing the UV sterilizer 3 days ago no algae film on the glass!!!! Yay.
