Hi everybody... i m seriously thinking about this CPX-PRO pump.
I look for silence and silence. i m sure this pump is powerfull for common operation. (sorry my english is dirty)

Is the DDC 3.2 + Top noisier than the CPX-PRO ? and compared to the D5 #3 or #4 ? I know the DDC 3.1 sound, and it runs ok for my ears.

I m a beginner in WC and i know there are PROs in this topic so...i ask

Thanks waterboys ^^
