I have a ton of media in my FX5 so I was thinking of dumping as much as I can in the HOB, and then just having either a foam block or something else for mechanical, and then add purigen to help with nitrates. My concern with the emperor is I dont know if I can fit all of that. From what I remember you have the slots that you put the blue pad that holds carbon and then that grey container that you can put whatever you want in it.
Frankly, I dont care about those two items. I just want to be able to stack pouches of my biomax which I am not sure I can do in the emperor. It just irks me that 2 AC110s will run me $160 and 2 Emperor 400s I can get for like $110.
