I have 4" of foam, varying thicknesses. Then a bunch of scrubbies and seachem matrix that I had in my canister before. After that, it is just heaters and return pumps. KISS. Is the tank crystal clear? No, but I don't mind.
I'd say look into foam pads, which make great bio media, or dollar store scrubbies. They both have incredibly value for bio media. Bio balls are usually used in a wet/dry setup, right? Mine is fully submerged.
