AWhen I go on vacation, I plug my Gyre Pumps into an outside power source away from Apex. In event of failure of Apex, water flow would continue and you tank would have some sort of water circulation.... Just food for thought....
Always have redundancy.
For example, my return pump is now plugged into a seperate socket and not on the Apex, as is one of my cross flows.
So if I lose the controller, I don't lose all the flow.
