I understand that but 400gph is the stated, it definitely doesn't push that much out when it's full of filters and media, I would assume that they run about the same in reality but I don't wanna run both, I wanna get rid of the emperor. I was thinking fx5 but I think that would be way too much current an they'd be all over the place, the 406 would be ideal but I like the g series too much, maybe the g6 but I don't really think that's too necessary either, I'm stuck between the g3 g6 or fx5 which is too powerful for sure
