its easy to take care of. My shaving brushes grow pretty fast. There good to have in a refuge.
They're wonderful to have but they aren't capable of providing the same level of nutrient uptake that much faster growing non-calcareous plants give. Plus halimedia and shaving brushes consume calcium and alkalinity. It's nothing some calkwasser and buffer or two part can't handle. Still, ordering cheato or culerpa, at least at some point, is the preferred option for most reef keepers.
Halimedia and shaving brush are usually valued as decorative plants.
