This drainage pump makes it easier to change fresh and saltwater in paludariums, terrariums, and aquariums. It is equipped with a 2.70 m long cable with a switch to activate or stop the drainage without having to manipulate the plug. Side and bottom suction cups allow the pump to be attached to the bottom or side of the tank, thus determining the water level to be drained. A removable protective grid safeguards the fish. The 2 m long vinyl hose and the water column measuring 1.80 m are also included. The drainage pump has a flow rate of 1000 liters per hour and consumes 20 watts.
