ok, so i have a 1st time planted 10g with only a couple plants in it so far. i hung a 24" fluorescent shop light w/ 2 17w T8 bulbs about 9" above the tank. everything looks brighter than with the stock hood which had 2 15w screw in tubular incandescent. what do you guy think of this? should i get different bulbs? i saw "grow" bulbs for this hood which specified for plants. are they worth looking into? they were also 20w each which i thought would be a bit much but maybe not 9" above the tank? sheesh i have alot to learn any help appreciated!
