Bubble Trap

Hey everyone I need some advice on bubble traps. I am currently buying my components to start my new saltwater build. Since I am new to saltwater I went ahead and purchased a CPR Bio filter model 194 which is rated for a 200 gallon tank. Since I've read that the bigger your sump is the better. I also bought a second a plain sump and had the manufacturer customize it so that it would tie in together.
My question is on the empty sump which will just be used for addition water volume and to house components like my heater, probes, etc. I have read and I've seen videos where a bubble trap have been installed in the sumps to reduce micro bubbles. So hears the question, would anyone recommend installing two bubble traps one at the beginning and one befor the return pump? I am asking because I have read posts where some have recommended doing two bubble traps. Does anyone have this on their sump? Would anyone recommend me to do this? If so any recommendations on the divisions? Should the return pump area be the largest division or it doesn't matter? If two bubble traps are not recommended t
How would you recommend the division for the one trap in the tank?

I know this is a loaded question but I'm new and trying to learn as much as I can from you all so that I can avoid as many mistakes as possible.

Thanks
Ed
