Blade Macro

Blade Macroalgae is a fast growing, green macroalgae that looks very much like seagrass when planted in the sandbed.  It grows from a root system, commonly called a “runner”, with the plant then growing from this system.  This root system will grow in either the sandbed or on the rockwork.  It can be quite fast growing, so if it is placed in the main display tank periodic trimming will likely be necessary.  It can also be placed in a refugium.  Regardless of placement, it will export nutrients when harvested. This particular type of macroalgae can be found in a variety of tropical and subtropical waters and grows in a wide variety of marine habitats such as lagoons, reefs and mangroves.  In a home aquarium, if not grown in a refugium, it can be placed on either the sandbed or the rockwork.  If placed on the rockwork, it will need to be held down with a piece of rock until it attaches.  Some hobbyists also report success in glueing it to the rockwork.

Blade Macroalgae is also a good food source for tangs or other plant-eating fish if kept in a display tank.  Like many other species of macroalgae this species makes a good choice for a refugium and can be kept in a display tank as long as its growth can be managed to prevent it from growing out of control.
