I am also a newbie and would be really grateful for some lighting related advice.
I have a 80 gallon tank, the dimensions are 48"x20"x20". The distance from the bulbs to the water surface is 4 inches. The tank is fitted with a hood so there is no room to rise the bulbs to a higher level. I bought 5 osram 54w t5HO fluorescent bulbs but after I read this thread (and 2 others) I think I may have gone over the top.
So i guess my question is: If i won't use any reflectors-only white paint- could I use all 5 bulbs without having excessive light?
Ps: I would like to grow carpet plants and some reds
