For maintenance of your overall bio-filtration, you should use a large medium-mesh sponge, along with some ceramic bio-balls or similar product, as your 'more or less' permanent housing media, to be rinsed occasionally.
For mechanical filtration, nothing beats double-layered filter floss, replaced with new product fairly frequently - suggest every 2 weeks or less.
I don't like the term 'chemical filtration', but Purigen is the best in this category, and it's all I use 24/7 - re-charged on a rotating basis (2 filters) every 2 or 3 weeks.
This, along with the filter floss, and fine mesh pre-filters on the filter intake tubes, provide the optimum water clarity, and pick-up/disposal of impurities.
