It is simple, you need to build bacteria. Without bacteria you get ammonia and ammonia is a killer to our corals and fish.
It is worse since shifting to dead rock vs live rock like we used to use because well it is dead and contains no bacteria.
Not to mention dead rock is first colonized by algae and cyano which can smother corals. Also dead rock usually is loaded with phosphates at first which leads to a higher level of cyanobacteria and algae.
People have different skill levels which may allow them to get away with a little more than others.
Patients is key in this hobby and why I have been in it so long and other are not.
Good things happen slow and bad things happen fast.
