This is a bit too powerful for the new tank, so I'm looking at getting the newer nanostream pumps that are a bit more appropriate flow wise. This pump is dead silent and in perfect working condition: ramps up/down smoothly. I would recommend this size pump for a wide 4ft long tank such as a 120 or a 125 and longer.
For aquariums from 200 to 2,000 l (52 to 528 US gal.) Flow rate: 2,500 to 12,000 l/h (660 to 3,170 US gal./h) Electronically controllable by all TUNZE
