How I usually do it is as follows : cycle the tank , wait 1 week after cycle completes to ensure u don't get another ammonia spike and let things stabilize, after the week I add either my smallest planned fish or a cuc if I still have some diatoms, then I wait another 2-3 weeks to let the bio-filter mature and adjust to the live stock. After those couple weeks I'll add some coral ( not
sps ), the most important thing is to add slowly so your system can keep up
