+1. I've found even some of the easy plants (cabomba, hygrophila, etc.) need the extra light to do well... I wouldn't do another planted tank without at least a pair of T5HOs over it. Algae problems aside, T8s just don't have the output for high light plants (IMO, any NO fluorescent will not be enough for a good planted tank, unless you're planting with mosses and ferns).
