I bought this pump to replace a pump of 120l of aquarium that was beginning to have "symptoms" of fatigue.
For 32, I am very satisfied, the pump once installed is simply inaudible, only 3/4 the rate is much higher than the original pump my tank.
the sytem of water oxygenation (adjustable) is a pleasant surprise and works very well.
Frankly for the price I do not see what more after so must see the last over time, but it's still a branded product Tetra.
