When I switched from a 404 to a FX5, I was surprised that the two baskets of biomax in my 404 filled up nicely one basket in the FX5. I think that was one large box worth + a bit. In Frankie's, I bought one large box of biomax, and ended up buying one more later, and splitting it between my two filters.
I can't remember exactly, but I think the large boxes are about 1000g, and the smaller boxes are 500g. I would say two small boxes or one big box per basket. It won't fill it up to the top, but 3 boxes per basket is too much. If you're putting it in two or three baskets, you can go 2 boxes per basket + one extra to fill up extra space.
