I like your light hanging setup. I've been thinking that my light was too high for a while now. Can light that is too high lead to slow growth? We've had injected CO2, good flow and filtration, and T5HOs since the tank started - and never had the fast growth that other folks seem to get. (Don't get me wrong, I don't necessarily mind not having
to trim ever 5 days). My wife settled on using window screen directly over the light over half the tank to deal with some algae on our anubias, but that setup you've got looks pretty sweet too.
Your setup has grown in nice, you should post another recent picture. Good luck on the cory eggs.
