Hey, good luck with your new tank!
I just broke down my same exact tank a few days ago, doing a 3 gal iwagumi of HC isn't easy. At least it required more attention than I was willing to give. Keep us posted, and here is my journal on it: http://www.plantedtank.net/forums/sh...d.php?t=111058
Also, got more info on how you automated the webcam/shots?
