Lighting Poll

[mark]

Comes back to the question "what do you want to keep" and "how big do you want to keep it in"?

Had a 75g FOWLR lit by 2-40W NO fluorescents, perfectly fine. Now I'm starting a reef, bigger tank, got a hi light clam, don't think I have any choice other than MH.

Current tank has only been up since spring but working for me is 2-40W NO fluorescents for dusk/dawn effect and evening viewing, 2-250W MHs, thinking now supplementing with either T5 or PC actinics would make things ideal.
