Media for 2 cannister filters

[jazmine]

I will be using a Rena XP3 and an Eheim 2028 for my 55 gallon FW tank. For those of you that use 2 canister filters on one tank, do you use one filter for one type of filtration (for example, mechanical) and the other filter for a different filtration (biological)? Or do you set up both filters to do both kinds of filtration? I am trying to decide which type of media to put in each filter.

Ive got both mine (fluval 305 and 405) running sponges and bio-rings on both.

in my planted tanks i run mostly just sponges. if you going to run sponges and bio media run them in both.
