Noisy Tunze 6100 on Profilux

[swiseman]

I have a pair of Tunze Stream 6100 that I am using on the Profilux. Since moving them to the Profilux they have become very loud. I have replaced the drives in a hope that that was the problem, however, there was no improvement. The sound is the the speeding up and down of the pump during the wave action.

Has anyone else experienced this, or, are my pumps just past their prime?

Providing you have set the 1-10V range between 3V low and 8V high so you have not been over driving the pumps there is nothing the profilux can do to generate noise.

are they vibrsting or have a bad magnet or the piece that swivels
