i have a emperor 400 and 280 so that leaves me with 3 media containers. i was wondering can i fill each one up with somthing diff or will that make whatever is in the container usless because its not enough of it. i was thinking about putting the biomax in the 2 containers in the emp400 and the diamond blend which is white and black diamond in the one container in the emp 280. or should i use all the same stuff for all containers
