Burning unwanted pests in reef tank

Hi I'm new to the forum and lasers. I'm wondering what laser you guys recommend I purchase to burn off unwanted pests in a salt water reef tank. Any help would be appreciated. I'm thinking a minimum of 2W. I'm located in western Canada
Thanks

Forgot to put this in my PM.
