i have two 1500LPH pumps and they are fine no dead spots. xenia can take over the tank  you can add more flow but your fishes and corals may get blasted around the tank. you may just need to buy 2 1500LPH pumps and get rid of the 3000LPH one, because with 2 powerheads you can even out the flow more. it just depends on what corals you are going to have if you are having sps corals you will need more flow. but soft corals dont need that much. im going to add some xenia to my tank some time next month.
