Rather than using your biofilter media as the first stage it would be better to use it just before the ammo chips. The more particulate matter you can remove from the water before reaching the biomedia the longer your media will last. Personally I use a layer of floss at each stage on all my canister filters. loss is cheap, effective and easily replaced. By putting a layer of floss at each stage my bio media has never had to be changed, a simple rinse in old water restores it to like new condition.
