+1 on getting the skimmer running.  It sounds like you've got a decent bioload in the tank to not have a skimmer going.  Also, give the corals some time, 2 days isn't a great indicator for judging the happiness of your corals, they're probably still aclimating to your lights.  You do have lighting that will support a reef right?
