Ok, I may have gone into Ludicrous Speed here- I replaced the 130GPH powerhead with a 550, pushing total flow to ~750 GPH including the canister (running only biomax and coarse floss, I know, canisters are for freshwater... stoopid LFS). 29 gallons, topped off to the brim with 205 can and HOB skimmer. And I think I *still* need more rock...
