lasers and wands

[Ram3500]

Hey guys, anyone have any success with with killing mushrooms. I have been trying to control them for years injecting all kinds of crap into them with minimal luck. About a month ago I removed a large rock and wire brushed the bastards off but they appear to be bouncing back. They are a nice green color but they are irritating my sps. Anyone try a Majano Wand? Lasers sound interesting but looks like hard to find for obvious reasons.
