Hello r2r, i have what i think is a pocillopora from a couple years ago get pretty big and mature.. over time started noticing it was growing in random spots in my tank... and unfortunately i kept letting it grow.... i took the mother colony out a couple months ago which was the size of a softball... now i still have the small colonies all over my tank.. any easy solution to this ???It is getting way too close to some of my acros and that does not make me happy... I'm currently experimenting with getting a piece of solid opaque plastic and covering a coral patch with it ( and putting a rock on the plastic to keep it from floating away )... and i dont think this is gonna be a fun road. hope someone maybe has some good tips.. thanks guys/gals
