Algae on Acan Rock

[HungryOven]

Hey guys. I have this acan with the most annoying algae ever!! Every few days, it grows long and covers the acan and I have to manually remove it. Is there an easy way to get rid of the pesky algae without harming the coral? Any ideas??

Get some zebra hermit crabs and put them and the rock in a glass measuring cup, in the tank. Make sure no food or pellets land in there. In a week or so, it will be clean. It is what I have done in the past, it really works.
