very good pump
very quiet @ powerful
great value for your money

Have to say this is the best wave maker I have ever owned. Extremely quiet and very powerful. I was going to buy Echotech but really glad I didn't, much cheaper and quieter. Recommend highly.

Funciona muito bem, recomendo para nanos

Really strong power even for 1m3
i'm greatly recomand it

Habe diese Pumpe nun seit Mai 2017 (15 Monate) und bin von der Lautstärke (kaum wahrnehmbar!) und dem fehlerfreien Betrieb begeistert. Ich kann die QP16 nur weiterempfehlen.

I took a chance on these and do not regret my decision at all! I got two of the qp-5’s for my 80 gallon. The provide more then enough flow and after about a week they were quieter then my mp-40’s. Worth every penny!

Bought two of these pumps for my new tank figuring the claims of how quiet they are were over stated... far from! These pumps are awesome and make next to no noise at all. I hear the trickle of the water in the tank of these!

This is an excellent wavemaker and absolutely worth the money.

The nightsensor is superb....
I have waves during lighthours and a steady flöde during night. Works perfect and NO noise
