Light recomendation

Hi,
I bought a used 45 gal tank that is 36"L x 13"W x 24"H it currently has a 36 in single fluorescent hood and a marineland singlebright 36 led. I want to stay low tech so I plan on filling the tank with low light plants, fish and maybe some shrimp. What do you think I need for lighting that would be the most cost effective? We will probably be building a wood canopy to go on top of the tank that will hold the lighting.
This is the tank: http://www.petsmart.com/product/inde...ductId=3804458

Go under the lifting section, go into sticky and check out the article by hoppy called par vs distance, there is a chart there that is easy to understand, that will tell you exactly the a amount of light and the distance from the tank the light source needs to be in order to achieve your needs

I have read that and I've actually read quite a bit on it. I find it all a bit overwhelming honestly. I'm guessing there is no bulb that will be sufficient in the fixture I have. I am new to all this and really just want to know what I need to go buy to achieve enough for low light plants.

Assuming 3" of substrate depth, that gives you 21" from the light if it's on top of your tank. You could get just about perfect low lighting (~30PAR) with this fixture.

I'm not sure what the PAR readings on my own personal T5HO fixture are, but I'd personally recommend it due to good quality. Its mounting legs would add about 2-3" more from the light at substrate level.

You can't get significantly more light from a T8 fixture by using a different bulb. Instead, you need to use a different fixture. You would get about the right amount of light from a Coralife T5HO, 2 bulb light - http://www.amazon.com/Coralife-08601...alife+lighting (the 36 inch long version) or a FishNeedIt T5HO, 2 bulb fixture - http://www.fishneedit.com/t5ho-3ft--...ium-light.html

Thank you! On the Fishneet it one what bulbs would I pick? Sorry if that's a stupid question but I really don't know. Do you know if microsword will grow under this light? My LFS said they need more light.

6500k. Microsword should grow fine. Supplementing CO2 will help as well.

The Odyssea is a great fixture for the price.

The Odyssea light would give you about the same light as the other two, perhaps a little more. It may be the most rugged of the 3.

Thanks for all your help, one more question. It comes with 1x T5 39W 10000K lamp 1x T5 39W Actinic lamp. Do I need to changes those out or will that work for low to med light? I also temporarily have a 26 watt cfl sitting right over the water in a clip on light to try and keep my hornwart alive until I get the new light. Using the hornwort just for it's beneficial properties. Won't be scaping the tank until I get the light.

I believe you can order the light with bulbs compatible with planted tanks, either 2 6700K or 1 of those and one roseate bulb. They will be much better than the reef lights you mentioned.
