Sump for 330gallon

T

So i am starting a 330 gallon tank and was wondering how big of a sump i need. I have 2 40 gallon tanks i was planning on making work but have also considered building a custom sump.Thoughts?
 
would suggest going to a single sump. 2 separate ones increases the build complexity and more chances for a leak
 
Whatever you get make sure to account for the volume change in your tank during a power outage. Due to how I do my return and overflow I probably gain 20-30 gallon when my pumps cut.
