Good chart.. But it lacks on what wattage of each tube. As T5HO is available in 2 feet, 3 feet and 4 feet length with 24Watts, 39Watts and 54Watts. Which tube is referred in the chart when they say T5HO?

1. It's crucial that all of the generated light is focused right into the tank. You will have to get good reflectors otherwise, a lot of light will be wasted, regardless of the wattage.
2. The lights can be staggered. If you have 5 t5s, you could set it this way -
Plants - Rocks
The 2 lamps on the right will contribute light to the left side and the right side (with rocks) will not look awfully dark compared to the other side.
3. Would be good to have at least 1 or 2 more t5s with your current setup. The t5 you have is HE (high efficiency) as opposed to HO (High output). If possible, try to get the 7000K-8000k ones. With higher number of lamps and a wider array, it may be possible to lower the height by 1-3 inches, increasing the PAR significantly (between medium and medium-high)
