Need help Plumping aquarium Rack

[Kenneth's Tropical Fish]

Hello Everyone,
I'm opening a fish store and have been building my custom acrylic tanks for my store and I want to make sure my plumbing is rock solid to prevent issues in the future. I'm looking for a simple system to run nothing super fancy. My tanks are set up on metal racks and will be running three tanks with dividers and one sump at the bottom. Each tank is approximately 73 gallons and each section is roughly 24 gal. Combined total system volume is 292 Gallons. I need help with how to run my plumbing and what size I should go with for my bulkheads and pipes. In addition I want to make sure I'm running the correct size pump for this system. Many thanks to you master builders I'm still learning. Ive made a legend in the photo to help understand it better. Tanks arent fully done yet

It's going to be really hard to get good advice for something like that. My best advice would be to make friends with your local competitors to see what they have done and maybe reach out to some of the professionals that post videos on YouTube.
