need advice for water movement with vortechs

[WarDog]

The QD's are quieter than the older WES model. I just installed a QD driver on my 1 year old dryside and wetside. I measured it to be 7 dB quieter. The thread is in the equipment section somewhere.

if sound level is your greatest concern, Vortechs are not for you...

You will find that they are very loud.

if you really need quiet, look at Tunze's instead...

Or if you plan on running an Apex controller these new Neptune WAV pumps should be out very soon and they look really promising.

I agree, you will always get some motor sound, if you must have a controllable wave maker you might consider Jebao RW's
