i have the following problem and i'd like your expert advice
tank dimensions: 40"L , 16"W, 22"H approximately 55Gallons
the tank came with a "light-glo" cannopy with 2 x 30W preinstalled fluorocent tubes.
i removed the above tubes and installed 2 x 55W PC fluoros (straight pin allignment). One at the back left and one at the front right. These bulbs are 22" long and as a result, there are some dark spots in the tank (back and front corners) where the light can't reach
i have installed reflectors too, but with no significant change.
ordering online cannopy/hood sets is out of the question due to high shipping costs.
from what i understand, this is not a good setup for the plants in the back corners.
i have in mind these options and i'd like your feedback and any new ideas
a. leave it as it is
b. build a new hood and install 3 x 55W PC fluoros (one at the left back, one in the middle and one in the right front) resulting in a total of 165W of light but might leave darker places;again.
c. install opposite of the 55W bulbs, 2 more bulbs rated between 25-30W to cover the whole lenght of the aquarium. This will result in 160W - 170W of light
