I have recently switched out my powerhead after a wav failed, I got a ticket from Neptune after a while trying to sort it via Skype I was told to simply buy another.
This didn’t go down well
So I sold up the other two I was using and the 1link.
I bought a couple of MP40’s and have recently been added to Mobius beta testing.
The app is fantastic imo
Simply drag a mode over in two the circle and set the speed, it’s Bluetooth but I never play with the flow if I’m not home.
It can quite easily leave the aquarium
