Thank you, VaughnH and Tom for your detailed responses.

Note, running these in pairs can reduce the light for most of the photo cycle, while you can still get a nice high light spike of 2-4 hours midday.

Would it be ok to run one 2x54w bank at 8 hours, and then have the second 2x54 bank run 2-4 hours for the spike? Or is it important to have both run equal times? It would be more convienent to have one run at the full 8 hours so i can piggyback the CO2 solenoid off the same timer.
On the other hand, is it really important to have the CO2 turn on an hour before the lights do? If it is, then I'd have to run a 3rd timer for the CO2 regardless..

It's got a 2x54W T5 set up and looks every bit as nice as most any high light tank scape you will see on the web.

I know which one you're talking about and I was very amazed by that tank.. So to achieve that, takes nothing more than ample fertilization and CO2?
I ran my 90g using the same lights (2x54w T5) for a while and then decided to add the 2nd bank of T5s when I got impatient waiting for the ground cover to grow in (glosso and HC).. Once they do cover the floor, can I cut back the lighting to 2x54 and still keep the same (but slower) growth patterns? i.e., without leggyness?
Would 2x54w be just as effective for me as it is for them, despite the difference in tank height (their 70g vs. my 90g)?
