You could just replace the standard breaker with an arc fault. It's my opinion that the gfci is the most important piece.

It's really smart to have multiple GFIs. You don't want to lose every piece of gear at once, especially if you are on vacation or whatever. Losing a powerhead isn't the end of the world like your whole system shutting down for a few days.

Greg pointed out on my DIY build that I only had one GFI. I was going to run everything through it, but I don't want to lose the whole system at once. My tank is fresh water, and a lot lower risk, but it's still a risk. I ended up getting six GFIs and pretty much splitting each item to it's own GFI. You can share low risk things like dosers, fans, etc. but your return pump, CL, skimmers, etc. should really have their own.

I also added a few switches so I can easily shut down my CL and return pump if I need to for maintenance without digging around and tracing wires.

It's also handy to use a labeller to label the plugs and matching cables. That way everything has it's place and is easy to unplug/ plug in.
