Around 40 micromols of PAR is a great lighting level to use - you get most of the advantages of higher light, and most of the advantages of low light, except that using CO2 is a very good idea with that much light.
I've awoken this post from the dead! I too have a 36 Gallon with the stock lighting 8000k bulb and just ordered a 17W Florasun 5000k bulb to switch out the stock one. Do you think this will even work for my Roseafolia , Anacharis Narrow leave and and other Anarcharis?

squidsquiggle I use one of these, inside a diy gutter fixture. I was lucky enough to have a local store that sold them, so it was much cheaper than the other options I could find. I do have to use co2, and I still get a bit of algae on the slower-growing leaves, but so far it's worked great for me. There's a link to the tank in my signature.

djscotty If you look at my picture, I was thinking the same thing but you cannot tell that the brace is even there. The light spectrum still looks even.

It does create a shadow down the middle. I saw on another forum, someone with this tank had cut out the black plastic brace and replaced it with plexiglass. I was thinking about it, but I won't do it unless I do it before I fill the tank because I'm too nervous about the weight of the water in the tank without the brace, even for a few minutes. However, I do remember them saying that they did the work while the tank was full, so it can be done. Sorry I can't remember where I saw it.
I don't know anything about actual effect on the growing of the plants though, this was just aesthetic....

Then you would need CO2 to keep the plants growing and healthy, or algae would certainly take over the tank. I think you would enjoy the tank a lot more, once the excitement of seeing fast plant growth goes away, if you used low light.
I guess what I'm worried about it that at my LFS they told me that I would really not be able to grow carpet plants without C02. I really do want to be able to do carpet plants, they make a tank for me. I am going to possibly do a separate thread about this, but I want to know what my options are, if there are any, to grow a carpeting without C02. Would Excel help? Or do I need C02, but low lights would be ok, or does it have to be C02 and med/high light?

azjenny Hoppy, one more question for you regarding this....
If I were to get the 4 bulb Fishneedit fixture (just using two lights at present), would I have enough with the 4 bulbs if I ever wanted to add C02? Or would I still need to supplement?

Last night Simon from Fishneedit wrote me back saying that they did have that as an option, so I might try that. Thanks so much for all your help!

Unfortunately the 30 in FishNeedIt fixture only offers white bulbs starting at 10000k and actinics. So I would get the 10000k only fixture and swap out one of the bulbs for a 6700k and then use the other 10000k as a backup when the other goes bad.

Titan, are you going to be doing Excel or no?
Yeah I plan on doing Excel. I bought a bottle not to long ago kind of as an experiment just to see if I would notice a difference. I can say I have seen faster growth after I started using it.

azjenny Also, what options are you choosing bulb-wise? There are the blue/white options and then the color temp options for the white bulbs? So confused
