I have 4 Eheims in the house and I use to run all that EFHIstuff in mine, minus the carbon, but found it all to be really unnecessary with a planted tank,
I have been running polyester fiber floss only,(changed ever two to three weeks) for well over a year, and found that is all that is needed for my heavy planted tanks needs, with great results.
I have never used carbon, from what I have read it is basically for non planted tanks as an odor eliminator, once it gets old it can cause problems by leaching.
