Yea, atleast a 100 gallon wet/dry.
A great way to play it safe is to do
LxW of the tank, and 4", what-ever gallonage is, get a sump that size
So you'd use a calculator and type in
8'x4'x4" would be 80 gallons, so if the main tank drained 4" at a power outage, you'd fill a sump up with 80 gallons of water. If ya figure your sump will have water in it already, so you'll want 100-130 gallons of sump space. Or something like that.
