Sounds good! Just the order of it sounded a little redundant. Basically your set up was doing: Take all solid crap out of the water -> convert harmful chemicals into less harmful chemicals -> take solid crap out of the water. The sponge is there to take out solid waste particles and will grow some good bacteria on it as well but primarily (in your setup) your other media is there for chemical filtration.
