Two separate systems in one house

[Brad Bessett]

Hello all,

I am currently running a GHL 2.1 doser on my main display tank and I am doing a new build for a separate tank.

So I simply buy another GHL 2.1? and add it to My GHL?

You can control any device via MyGHL. You only have to register the additional device in Myghl.
