yes but that is one of the problems, it likes ( not all ) to be planted. meaning you have to disturb the substrate to trim ( so it doesn't go sexual ) or risk releasing toxin ( not all but... ) by trimming in the tank.

if the macro is being consumed in the tank the nutrients are just being cycled but never actually leave the system. you need to trim and remove the macro to actually export nutrients.
