Although T5HO are bright, I doubt you're registering high light at the bottom of your tank (with those plants its probably even the entire bottom half).
Even in your picture, its pretty clear that is fairly dark at the bottom.
In any case, i don't mean to distract anyone from the gorgeous tanks, including yours 1aqumfish!
Thanks for sharing.
