Thanks for that Ganowicki. I for one think that inacndescent conversion is a hell of an idea. I tried it once with PC bulbs I bought at Ikea. They were $5.95 each, but very low in kelvin. Our LFS now sells spiral PC bulbs made by Aquatique. The 15W is $23.95. I have one over my CPR Refugium. I will have to see if Albright lighting is in Calgary. It sounds like you have a ton of light on your nano. I myself have four 13W PC's I bought at AH Supply in the US. When all was said and done I think I was out about $200.00 for the light. Right now I run two of the lights for 26W total, but there is only Xenia in the tank, and a lot of daylight. The tank is only a couple of weeks old, so I am not putting much in for awhile. :D

Those spiral bulbs....are they weather resistant ? I would be a little cautious since salt spray or a little water can fry these bulbs if they are not weather resistant.

I use one of the outdoor CFL bulbs that you can get at home depot -- the 6500K ones.

I have modified the original hood so that I can fit the NO and the 2 PC into the designated light section. As you may know, the original hood seperates the lights by a piece of glass, therefore no moisture wil get in. when I get my hands on a digital camera I will take a photo to show you.

Probably not, but I always use glass covers. Just a phobia of mine. :D
