Shaving Brush Algae

Shaving Brush Algae (also called Shaving Brush) is a great addition to any saltwater aquarium because it is a hardy algae with high calcification meaning it won’t be getting eaten by any critters. Shaving Brush is a macroalgae from the family of penicillus.


Shaving Brush Algae can grow up to 12” in height with perfect conditions. But usually, Shaving Brush Algae will grow to about 7”

Ideal Growth Conditions

Shaving Brush plants require water in between 72 and 80 degrees Fahrenheit. They prefer a pH in between 8.1 and 8.4. Shaving Brush Algae will grow fastest in sandy substrate with high lighting, however it will survive and grow slowly with a coarse substrate or lower lighting.

These types of algae will knock over or break with high flow rates, however moderate indirect flow is necessary for a healthy plant.

Shaving Brush Plants also require calcium for growth and it is recommended to keep your tank calcium levels in between 350 and 450ppm for optimal growth.
