I am planning on buying two of the #2 or #3 and putting them on opposite sides of the aquarium and alternating the flow with my ACJR to give a wavemaking effect.



I have a question:



In order to keep my equipment as quiet as possible, will the pumps make annoying noises when starting up 3 or 4 times per minute.

I have heard that they do make a little noise when starting up, and I don't want any clicking noises to bother my wife. I have been able to change things around to make my aquarium nearly silent, and I want to keep it that way.



What have you experienced (especially those of you that run them on a current device)???????
