Have a case of black beard algae on my hand so I figured I would go through the process of how to spot treat black beard algae with Hydrogen Peroxide and Excel. Both are great methods that gave me positive results.
Note: I do not recommend using this on any mosses and as always be sure to monitor your plants and fish for any odd changes.
