You need at least 22.5 Watts. I went with a 40 W UV sterilizer connected to the return
Of an FX-5. Whatever you get, you have to match the recommended flow rate of the UV.

I have the same setup and was wondering the same thing..........

You could use a pump at the recommended flow rate, or use a canister filter with matching flow rate and have some additional redundant filtration. The only thing to keep in mind is that you don't want to exceed the recommended flow rate of your UV sterilizer. The bigger the UV, the faster your flow rate can be. For instance, I'm going with two120W UVs run by Barracuda pumps through Ultima 4000s on our new system.

I think 36 watt would do nicely, I would probably just hook it up to a smaller pump with prefilter, but you can plumb them to canisters too.

there was a guy ( cant remember the name) realy into his UV.there was a formula he used was like 1 watt UV to every 10G of water and flow rate was UV wattage x 10.

Here's an excellent article on UV sterilization.

For Level One Sterilization, at a turnover rate of 1.5 times per hour with a flow orate of 20 gph per watt: 450 gph divided by 20 gph/watt = 22.5 watts. So a 36W UV sterilizer would work.

With floor to ceiling picture windows and two large skylights in our living room, our tank is in sunlight all day. Our 300 gallon tank soon looked like this:

A 40W UV sterilizer quickly cleared up the green water
