Top Off container - What do you use?

[Ratpack]

Thinking of building a auto top off container for my future system of 75g with 30g sump. Thought I would get a few ideas from the experts out there. Photos would be nice if anyone has them.

I simply use 5 gallon buckets for all my water needs.

Scott, so for top off, you just sit a 5 gallon bucket near your sump or do you just top off manually each day?

Right now I am topping off manually with my RO/DI (feed water runs right to the sump) however I have an auto topoff unit to setup and when I do it will be setup with a 5 gallon bucket as well. The RO/DI will keep the bucket full and when the tank needs water the unit will turn on an aqualifter pump to replenish the tank.
