sorry don't think your filter media will work. Try this 1) top layer
1. wool
2. poly filter (chemical filtration)
3. bag of charcol
4. wool again
5. 7 inch of #1 corals
remove your ring and bio ball don't think this will work. My 4 ft tank started introducing fishes at about day 14, corals day 7. Now I am at day 22. Have about 12-15 fishes.
