I agree with Joker. Please wait. If you want to add things now you can start with part of your clean up crew. Noticed you used dry sand, now is the time to start seeding that also with life. If you can find a close reefer that has a sandbed see if you can get a scoop of sand to help add diversity to the sand in your tank. If you cant find someone you can look at indo pacific sea farms, spaghetti worms are great (they have them listed as Mama Mia Worms.)
