How could I get rid of Grape Macro Algae!

[BlueWorldAquatic]

I had a major problem with the same alae in our SPS tank at the store. We pilled it out daily, tried emerald crabs, and tangs & foxfaces. As long as the roots are still in place, it comes back very fast.

The solution I came up with is the following;
1 - pick off as much as you can
2 - Soak it in HOt (not boiling water) for about 3 minutes
3 - scrub the rock
4 - let the residue dry a bit, then rinse in salt water

we havent had the problem since.

Ask Bean, I had her scrubbing with me most of the day.
