Pump works great and has plenty operationa modes.
In the beginning confussing with the controler, but when your used of it works like a charm

I'm a huge Fan of these gyre Pumps, especially for my Cube Tank where I have one vertically installed.

Lots of flow! Sadly mine isnt nearly as silent as seems to be the case for most people including my father in law who got his pump at the same time from here. Mine makes whining motor sounds.
