Yup, that's what I meant (and where I got the idea, though I see it's been updated since I saw the page last
). I've been pondering how to do it using the 70W metal halide ballasts I have, I love the Japanese tanks that are lit with spotlights...
And this is looking pretty interesting, now that's there's water... maybe you should do a non-photosynthetic system?
