EHEIM Quick Vac Pro gravel vacuum for cleaning your aquarium wirelessly when you need to remove the visible debris at the bottom of the tank without removing water. Selling because I do not use this anymore - I have become overrun with babies, and I always end up removing water from my systems. Comes apart into three pieces. There are a couple of cracks in the plastic where two pieces meet, and these can be repaired with liquid cement or epoxy. Even with the cracks, this works perfectly. Sleek black handheld design. Clear collection chamber. Easy one-button operation. Ideal for keeping aquarium gravel clean.
