I had the Sattellite 65 watt fixture but the Coralife is basically the same thing. You can find a freshwater model of the Coralife too with the correct bulbs.
I like 29 gallon tanks in general. A little bit narrow though. 30" for some reason tends to be a difficult size to find lights for, especially for a 29 gallon. At 65 watts you're in the mediumish range but some foreground plants might struggle. At 130 watts you're blasting a ton of light into the tank and have to be at the top of your game

Hopefully I get awesome plant growth!
