I tried searching the Aquabotanics web site for the article you referenced
but I could not find it.
From your description, I am figuring you have two rows of CF lights in the
back 1/3 of your tank and the lights are fairly close to the water. How
do you think your lighting would work if you raised it 9 inches?
Currently my light enclosure has individual inverted 'W' shaped reflectors
for each T8 bulb. I also have a grid in front of the bulbs to redirect
the light straight down. I have tried to optimize the available light
that the plants receive but I am still not happy with the results.
I really would prefer having a fulling open tank and not have the lights
sitting as close to the water as your tank.
Thanks for the input,
