Redo Plumbing and SWCG Install - layout recommendations?

[AZGeekster]

Pool: 10k gal Inground PebbleTec
PUMP: Hayward SP3400VSP
FILTER: Hayward C3030 CF
Single waterfall water feature, Hayward Navigator.

Purchased a CircuPool RJ30, need to install that, and wanting to replumb the above ground plumbing. The visible PVC loop bottom right in photo is where the chlorinator was removed. The open 2" pipe is the Hayward navigator and will be plumbing that up with 3-way jandy. I want to put unions to make things easy, but wanted input on if I should change the layout of the plumbing for flow efficiency?
TIA!

I would remove the red and blue manual valves and replace with a Jandy 2 way valve if you need them. what does each pipe go to?
You can consider putting the SWCG on a vertical pipe if you want to enter at the top of that tee.
