the hardest part of frgging your corals is actually getting yourself to do it. Nothing like taking your frogspawn out of your tank and snapping off one of its arms. Or taking a chisel to your plate coral and cutting it up like a pizza.
I just recently fragged my hypnophora. Fragging soft corals does nto seem to as big of a shock to your (being you not the tank) system. Its when your are deling with hard corals it gets harder to make that first plunge.
What everyone said on here is true. Super glue gel has been proven to be reef safe, people on here use it all the time w/o negative impact on theiur systems. However, if you do not feel comfortable using super glue on your corals, they do make a reef safe epoxy. Its works good too. Infact I like it a lot better for securing bigger pieces of coral. Hope this helps,
