Legend Avernus AlBlackEX™

Legend Avernus AlBlackEX™ was specially designed for the control of Black Beard Algae (BBA) in planted aquariums. This type of algae is not only unsightly, but fast-growing, and will quickly spoil the natural beauty of your fish tank. In order to help reduce stress within your aquarium, we recommend maintaining a healthy environment by providing nutrients such as those found in our Legend Essential™, Legend Heaven™, Legend Ancestral Phi™ & Legend Entity for fast recovery. As the plants grow, they naturally will strip the key nutrients required by BBA helping to slow growth rates.

Legend Avernus AlBlackEX™ is a highly effective means of removing BBA when combined with healthy water conditions and algae-eating inhabitants.

Legend Avernus AlBlackEX™ has been manufactured with only superior-grade raw ingredients.

We generally recommend a water change of 25% to 50% per week in aquariums. After the treatment against algae, use Ancestral Phi™ to reduce stress, to encourage rapid growth and the plant’s recovery
