Which Biomedia To Use?

[storm45]

Hi, i recently watched a instructional aquarium setup guide, and the person suggests using Matrix Biomedia (http/www.bigalsonline.com/BigAlsUS/ctl3684/cp18401/si1380232/cl0/seachemmatrixbiomedia1liter), my question is, which is better, the matrix one or BioMax (the cut up tube ones, like pasta)? I currently have a Fluval 305 external filter. thanks
