    Hi all,
    I am currently running the Fluval Hagen 206 canister filter on my 20gallon tank. The current media is:

    · Mechanical – 4X Foam Pads; 1X Polishing Pad; 1X Bio Foam
    · Biological – BioMax Ceramic Rings; Evolution Pure Aquarium Balls
    · Chemical – Activated Carbon; JBL BioNitratEX

    It's coming up time to change my carbon and I was just wondering if carbon was entirely necessary and/or if there was something better that I could be using in the chemical filtration part of my filter (top level)

    Yep, not necessary. It will help remove impurities, as mentioned. Really good for removing tannins, if you need to remove medication, etc, but as an always-in thing, not a requirement.

    Carbon isn't necessary unless you need to take out chemicals from the water. When doing any medication it can actually be a hindrance as it would remove the meds form the water.
