Fluval G3 customization

  1. ReCause5764 Member Member

    Bought a G3 today (for only $100 brand new!) set it up and it works great. But I noticed you can customize the chemical filtration which came in a cartridge form but apparently you can use loose media as well. Just wanted to know if anyone knows a good way to customize it or yalls experience with G3s in general.

    I don't have a G3, but I like to use polyfill as mechanical filtration and ceramic media as biological filtration. I don't use chemical filtration.

    What kind of chemical filtration does it come with?

    It's comes with carbon, but you can also get a cartridge that takes care of phosphates, one for nitrates, and one that has a little bit of all three. They also have an empty cartridge that you can fill with whatever chemical media you want.

    You can remove those if you want - none are necessary. I don't use chemical media in any of my tanks, and I have no issues.
