There's far too many options, but around 100 gallons is about right.

I'm planning on using 55 gallon plastic drums on my expansion tanks ( 2 300s and 225 ). It'll allow me to maintain the sump water level at tank water level. Unique design with concentric circles inside.

Sounds like a cool idea... Can you give more details?
