To be honest, I think having 2 filters don't necessarily mean better filtration - especially if the filters aren't run properly.
What type of filter media to use depends on what flora and fauna you'd like to support and what water parameters you'd like to maintain.
Nonetheless, it's good to have 2 filter in case one of the two breaks down!![]()
Bro, are you using the original blue sponge? Can share your layering of the media in your 2213?

http://www.eheimasiapacific.com/prod_e_media_setup.html <- I follow the setup here for 2213. But, i skip the 1st layer of putting mechanical filter media. My 1st layer is the original blue sponge which also does the same thing as the mechanical media by trapping large/medium debris, 2nd layer is eheim substrate pro (around 1 litre) to cultivate bb and lastly the white sponge (fine filter pad) to trap tiny debris.![]()
Thanks Kenzai. i was toying with either the blue sponge or CR as i find the CR traps more big bubbles and the flow is lower than the blue sponge. Ok, i'll dump the CR, wack more substrate pro.
