Shaving Brush Plants are some of the most diverse types of macroalgae in terms of appearance. Some have spherical tops while others are taller or more like a barber’s brush.
However all have a bottom stalk that attaches to an anchor set in sand or other substrates. Unlike the other types of macroalgae we’ve discussed so far, Shaving Brush Plant is a calciferous species. It incorporates calcium into its body, making it unpalatable to most herbivores. A dissolved calcium concentration of 350-450ppm is ideal for growth.
The height can vary, from 4 to as much as 12 inches. Most species prefer sandy bottoms for rooting, moderate to high lighting, and moderate current as they prefer growing in very shallow waters.
