What upgrades are there to add?

[Gools]

I'm doing my electrical in my fish room, trying to count how many plugs I will need and I am trying to think of what upgrade I might add in the future, so that I won't have to run extension cords. Kind of a hard question to answer. But I have all the basics, skimmers, calcium reactors, kalk, lights. Any other toys that I might have forgotten.

Thanks
