Hi,
I'm intrigued. What watt light? incandescent or compact flourescent (to save on electric) or doesn't it matter? How do you make the light and housing water tight from rain? Do you run it all night to provide maximum bug 'production' for the fish? Is there an intensity difference that matters (in other words how close to water surface is best?)

Someone said a bug zapper would work too but will fish be interested in live bugs over dead ones?

Thanks!
