Hi All,

I have a 40 Gallon SeaClear System II tank. The included hood sits in
the opening of the aquarium. See
http://www.petsmart.com/global/produ...52444177 8940
for an image. The problem with this hood is that it only holds a 24"
bulb which limits me to 2 x 20 Watts. Looking at my plants, I have a
feeling that that's not enough ;-) Is there any way to put 2 x 40
Watts into a 24" hood?

Sure if you switch to compact fluorescent. There are 18" 40W biax tubes.

This is what I've standardized on here. Warm whites are plenty good enough
you don't need anything fancier than that - to say nothing of the evidence
that everything fancier doesn't actually work as well - plus because they're
a more or less "standard" - that is sued in industry a lot they can be had more
cheaply than the Asian made pet/fancy/expensive tubes.
