I am planning on seting up my first planted 29 gal. aquarium and i wanted to go with low light plants with 1.5-2 watts of light per gal. no co2 and a glass canopy. What kind of light would you suggest? I have been reading about the power compact lights, but i am not sure which one to buy or the size i would need to fit over my 29 gal. I also have read some people say the 6700k bulbs give a yellowish tint to the tank, is this true? Thanks
