As per jorian's review below, you may need a bigger version if you need to operate towards the maximum flow as mine is running flat out, but does a great job.

Hatte vorher ein deutsches Markenprodukt und würde immer wieder diese Pumpe hier vorziehen. Einstellungsmöglichkeit auch sehr gut. Empfehlenswert!

Just installed this pump. The first impression is WOW! This thing is powerful and dead quite! Don't know how long it will last though.

Nice light,good price

Delivery was a bit slow but other then that the item was great

Super pompe, silencieuse, efficace, je suis très satisfait et je la recommande !!!

The pump has been in use a few weeks. Its silent and strong. I like that you can adjust the returnflow easily. A great pump that is good value for money.

Great Product, very quiet, sturdy build, with lots of options on the controller.
A must have for marine aqurium.

this return pump is so quiet you can hardly hear it. Ive tried many but the build quality and low noise level is amazing. I do recommend going with a more powerfull of a pump as what is recommended on the site. This one does the job for my 125 gallon but fully open and supported by jabeo wave makers.
