the grille bit comes off
you can sometimes take the grille off and attach to a stand pipe for undergravel filter
you can also use it to pump water to an overhead filter tray on your tank
put it in the tank and point it in the direction you want the water to flow :lol:
it should have a coarse sponge inside it
could also, dependent on size, be used as a sump pump
