What upgrades are there to add?

FWIW I have 5 electrical lines going to my tank.

I have two return pumps, they are each on a separate line, if something blows one line, I still have circulation in the tank.

My CL pump is on yet another line, same reasoning.

My Halides are on another line, I don't like the surge in power they take when they start-up. I know they start up one at a time, but what happens if the power goes out? then when the power comes back on they all start at once.
