UV Sterilizer (Best one out there)

[GrndHog]

I'm going to purchase a UV and was wondering if one brand or style was better than the other. This is going on my 150, so I was thinking a 25watts?

How much would this warm my tank temp?

TIA

I would go with a 40 Watt sterilizor and get the pentair Aquatics or Aqua ultraviolit
