My setup is similar to Coleus's, I use a reservoir that is 30 gallons with a tunze ATO and my sump has room for about 15 gallons of spare water in it. So in the event of a float failure the maximum amount of water on the floor is 15 gallons if the reservoir is full. 30 gallons in the reservoir will go about 2 weeks before it needs a refill. Long enough for a short holiday. Ideally the sump would have excess room for the total reservoir water.
