Montipora grow insane in my tank. But why?

[Seansea]

My tank is 7 months old and the thing that grows the most by far is my montiporas. Not zoas(in fact struggle bus with zoas) not gsp, not euphelia or acans. Not even mushrooms. Def not my sticks. Montiporas man. Is this normal or is there something in my tank making this happen? Think they are going to be more of a nuisance than my gsp.
