Almost ashamed to admit it but I think I may go with this eBay auction # 300620093692 - it's one of those cheapo Beamworks/Beamswork LED fixtures. But this tank is just 7" tall. So the light would be just five or six inches from the substrate. And it's only $35. WAY cheaper than the Marineland equivalent.
Surely it could handle mosses and crypts?
While it's really low light, something tells me I'd even be okay with suspending the fixture above the tank a bit.
What's the worst thing that could happen with it? I mean, I've already cooked one tank this week. Might as well try screwing up another one.
