Sump Size for Custom Tank

[N11morales]

Hello I'm planning on getting a custom built aquarium that is 72x25x24. Roughly 180G
Also the stand will be 72x25x36.

I was looking for a sump that will work for this tank?

I would like to have space for a reefmat 1200, refugium, skimmer section for a reef octopus regal 250int 10" protein skimmer and media reactor, then chamber for return pump.

Any suggestions on a sump that will work for my filtration or custom build. I'm open to options.

A 60 gallon breeder tank with a baffle kit? Then size the chambers as needed.

+1 on a tank with baffle kit. Probably somewhere from 40-60 gallons.
