This may sound crazy but I'm having a huge problem with Green Stylophora. It's popping up every where. Little patches I can pop off the rocks and glass as soon as I see them but they are beating me. Once they establish a foothold it's near impossible to scrape or pry off. It's worse than aiptasia in my opinion. they are aggressive and once the touch another acro it recedes. I'm looking for advice on how to eradicate or at least control this pest coral in my tank.
