does fragging off the infected RTN frag help?

[andysho]

how many of you who do that

does it helps a lot?

[FuEl]

It helps..but you must frag it so that all infected areas are removed. Meaning you frag it way above the receding margin. But if the sps is already stressed in the first place and is undergoing rtn..fragging can only be said to be a 50/50 gamble to take...You either leave it and hope it stops or you frag it to know at least you attempted to save it... It's always best to frag a healthy coral.
