Pond UV different than a Reef UV?

Kind of like tanks on Craigslist? Not drilled but good for salt = 3x the price

Yeah so true! "here's my regular 30g tank with HOB filter and a half bag of salt, no skimmer or livestock....ASKING $1000"

The rating is very very different.

For QT sterilization you want 90,000 µw/cm2.
You need to match the light output and the flow rate to get this.

For example, our UV sterilizer:
30,000 µw/cm2 (EOL) 35,000 gph
45,000 µw/cm2 (EOL) 23,333 gph
60,000 µw/cm2 (EOL) 17,500 gph
75,000 µw/cm2 (EOL) 14,000 gph
90,000 µw/cm2 (EOL) 11,667 gph

This same UV sterilizer will clarify a 100,000g pond

When a UV sterilizer is rated for pond they give you the pond volume that it will clarify.
Call the manufacturer and ask what flow rate you need to pass through it to give you 90,000 µw/cm2 and this will kill everything down to the protozoa level and stop disease in your qt system.

90,000 will not kill ick, I have seen the requirement for this is 280,000??

The difference generally is the pond UV is much bigger than those designed for ponds. Mine was huge 24'' 55 watt designed for pond. It did not kill what ever was on the fish.
