Small pump, ideal to create water movement in planted aquariums where space is going to be an issue.
Ensuring you have sufficient water movement is paramount in a planted aquarium - one filter is never enough to move water around and this is why you need a second pump to fulfil that purpose. If your CO2 is not being moved around enough then nor are your fertilisers which means that your plants will not be getting enough CO2 or nutrients (end result algae growth). You may already have algae problems and this could help your situation.
Easy positioning thanks to the patented magnet-suction cup support.
The sphere joint and the flow control allow to direct water as necessary.
Flow rate of 650l/h and uses 4.5W.
