Aqueon uses a proprietary cartridge, much like many other hob filters. That blue grid media holder is supposed to provide a place for nitrifying bacteria to grow, as if they know that, and allows you to change the mechanical filtration out without affecting the bio filtration, in theory. This is similar to the frames on Whisper filters. IMO both of those filters suck. AquaClear hob's have the sponge & such as stock media, though you can fill them with pretty much anything.
I'd toss the Aqueon media in the canister, toss the blue frame in the tank where there's some water flow for about a week. Fast the fish for a day before the switch, feed lightly for the next week to avoid any cycling issues.
