Forum » Wavwmaker 4

Hi I have 1 set including 4 pumps running and the two small model 3 make a lot of humming noise when at full speed. Fan i wavemaker also has lot of noise. System must be shut off when we sleep in house even though aquarium is 20meters and two doors away! Can wavemaker fan be changed to better an are pumps this noisy???

Hello, In ref to the Wavemaker, please make sure that the product is positioned so that there is enough air exchange and the temperature is not to high, this will prevent the fan from going on too often. Aslo, make sure that the fan is clean and free of dust. In ref to the Koralia 3 making a humming noise, please make sure that the two bushings are positioned correctly, one should be on the rotor (white one) and one should be at the bottom of the rotor chamber (black one).
