Thank you for your sharing of your valuable experience!
Its true that some SPS lovers tend to be more inclined towards P.E. (I admit, im one of them.)
However, with your sharing, i finally understand that its not doing much harm to the SPS as its only nipping on the P.E. portion and not the fresh.
Anyway, its already roaming freely in my sump with lotsa algae for it to feast on.
