Thanks everybody! Ok so a box or two of biomax in the 2 bottom trays, and what is the best to put in the top? Or, any other suggestions?

If you fill the whole thing with BioMax that would be your best bet. Biomax channels the water in different directions to allow the most contact with the media. Bio balls and scrubbies allow the water to pass straight through.
Personally, I think scrubbies are worse than bio balls in any application. Thats just me though.
