Yeah those plastic plants do look pretty cool i must admit, make sure to clean off every last little bit of the bleach because your live stock (if your having any) wont thank you for it What glassware you getting?
I am WELL IMPRESSED with those plants mate... you might be starting a new craze !!! LOL. I would like to see some carpet type plants coming down between the smaller rocks over to the right and then continuing over to the right side of the tank and maybe a little forward. I think that would give the impression of greater length.
