So my new canister has about 12 inches of empty room at the top. It is a odyssea cfs 14i. This canister pulls from the top down. What I have in it now is 3 different types of foam and about 100 bio balls. (Stock media)
What I am wondering is what I can put in the filter to utilize that 10-12 inches of empty space.
