Has anybody ever used spongies or bioballs in a canister filter? Or should they only be used in a wet/dry system? I have a spare FX5 that I want to add to my tank but I don't want to go broke buying fluval biomax. It came with the sponges around the outside of the baskets, but no media for the baskets. Thanks in advance for any suggestions.
I need some suggestions on media for canister filters

For larger filters I like Pond Matrix. Much larger size. Throw it in a laundry bag and pull it out all together.
Bio balls would work but in a fully submersed situation it's not as effective due to its lack of surface area. Bio balks are more for wet dry set ups.

I use lava rock in all my filters and it is awesome. i have it in my diy filter for my 125gal south american cichlids i filter 1000gpm and have about 8lbs of it in the wet/dry filter. and about 4lbs in my ehime 2217 canister that is in my 75gal tank and 5-8lbs in another diy filter for my 55gal angel tank that filters 500gpm. all of the tanks are clear it looks like my fish are floating in air. and my water is perfect every time i test it. I will never buy bio media again.
I sometimes use some lava rock here and there. Just cuz i happen to have a huge bag of it. Its a cheap alternative for bio media. Its definitely not as good nor as porous. Common sense says so. Take a look at a piece of lava rock then compare to some ceramic rings. Ceramic rings have microscopic pores. Lava rock has huge pores. Thus ceramic media can hold more bacteria. Cuz smaller pores = more surface area = more room for bacteria = more efficient media = better than lava rock.
