Handy compact pump with siphon kit for water changing and substrate vacuum cleaning.
Simply squeeze the pump and the water will automatically flow up through the tube into your bucket.
Comes with a detachable suction tube for removing waste from the gravel or substrate and a protective guard so you don't suck it away. Whilst the water is being siphoned up the tube, plunge the end of the siphon into the gravel and gently pull it away, this way all the debris in the gravel will be sucked away.
No need to take a mouthful of tank water any more!
