Lighting a filter

[fortheloveofcrabs]

Hey,

I know that some of you guys out there have done this (ahem Bob_I)... I have a 2.5 gal on my desk at work and I would like a little more water volume. I have an extra Fluval 304 at home and I would like to use it as a sump... Errr refugium rather. How do you internally light one of these guys? Furthure more, what kind of bulb did you use? Some insight would be really appreciated.

As well, has anyone out there ever made a skimmer out of a 2L pop bottle? Attach a powerhead to it and BOOM! A venturi skimmer! Any experience?

Thanks!
