Yes when I set up my current tank I was planning on going bigger one day so I have had the structural support in place for well over a year now for this new adventure lol.
Right now my ATO and lights for service under the tank when the doors are open
I will have a float switch in the over flow to shut off the pumps in case the pipe stops up.
And my skim mate container has a switch to shut off the skimmer when it is full
