How much light do you need for a refugium?
My refugium is 20"x9"x15" ~11.6g (actual water volume) What size light should I use? I'm considering a used light but I have a couple of options... both lights are PC but one is 40W and one is 80W... which one should I use?

A plain old clip on desk lamp with a cheap screw in bulb works just fine and much cheaper.. But out of the choices above go with the 40 watt.. Half the power with the same results..

Kind of what I was thinking...

This is the bulb that Cameron and Brandon worked out a couple of years ago. I have been using one (time to change) and my cheato liked it.

lacking light is why most refugiums don't work. People skimp on the light and they jump to say "this system doesn't work" I would check the used forums to find a cheap used PC or t5 fixture. Is it the minimum you can possibly get away with? no. But you'll be glad you did when you're pulling out bowling ball sized clumps of chaeto each week and green algae cant even grow on the sides of your refugium, let alone the glass in your main tank. please don't sell yourself short on the light. thats what runs your refugium.
