Trouble with VorTech controller and MP10's

[Robgixxer]

Hello everyone, i'm new to the world of GHL. I just received my new vortech controller yesterday and i can not seem to get the pumps to link to the controller. is there something that I am missing? no matter how many times I try they will just not link.

Hi,

if your pumps have already a Mobius-ready firmware installed, you need to downgrade them first: https://www.aquariumcomputer.com/knowledge-base/ghl-vortech-controller-and-mobius-update/
