You can lower the water level in your tank as much as possible, and directly spray this solution on the algae you want to destroy.

Or, you can take your plant right out of the aquarium, and dip the foliage that is covered in the algae into the diluted vinegar solution you have made.

If you do this, make absolutely sure not to get any of the solution on the root system of your plant. This will harm or kill the plant!

Before putting the plant back in your aquarium, be sure to wash them with the same water you plan on putting in the tank, to ensure that all vinegar is washed away. Vinegar can affect the PH balance of your aquarium and cause problems if you aren’t careful.

How Does Vinegar Kill Black Beard Algae?

Simply put, there are ingredients in vinegar that are deadly to Black Beard Algae. That harmful ingredient is acetic acid. Being exposed to this for a period of time will kill almost any algae.

Of course, this means that vinegar can harm the plants you actually want to keep around, but as long as you do not expose them to vinegar for a long time, they should be fine. Most plants are a lot more robust than algae is.

The main thing is that algae requires a delicate PH balance in order to thrive, and being exposed to acid upsets that balance, thus causing the algae to die relatively quickly after exposure.
