Ok heres the problem I have this nice soccer ball size piece of flat live rock that iv been saving clean to have a nice sps mother colony grow on, the problem is that the mushrooms with thier mind of its own drifted in holes on the flat rock and now i have 3 mushrooms growing outta the flat rock, they are in the holes reacing out so its not like i can chissel away the mushroom so how can i get it outta there and if theres no other way how do i kill it without killing other coral? I did not wanto kill it but it will kill my sps when they grow all over it.
