How to stop an encrusting coral?

[crimper]

As Frogger said, Acros dether them from taking over. I have the same problem when my Christmas monti had a growth explosion, however as soon as they touch the Cali Tort and the Purple Bonsai, they got bleached out.

So put an acro frag over them and let the acro encrust and demolish them.

My latest one is my Setting Sun Monti trying to take over but my Purple Bonsai said... Ahh ahhh.
