240 cube sump?

[fishpimp69]

What is the minimum size sump I can get away with? I have limited space were the sump will go and might be able to fit two smaller tanks like a 45, and a 38. Total of 83 gallons. Would this be enough?

Well the answer is the largest that will fit in terms of room under your stand. So a total of 83 gallons should be more than enough.
