Need help with a DIY Auto Top Off

[juice_1080]

after dealing with adding 2gal every 3 days to my tank for the past month I have come to the conclusion that I need and ATO system but I don't know where to start. I know the obvious things like I need a float switch, hanger, and pump. Where can I find an electric float switch though? I already have a spare pump and 10g tank laying around and building something to hold the switch will be a breeze but I guess I just don't know where to look for a float switch. It can't be gravity fed either since it will be at the same height as the sump.
Can you find float switches at places like Menards or Home Depot?

Did you need anything more than the switch, pump, tank, and bracket?

Hey what's up! I use the JBJ Automatic Top Off it about $80.00 but it works! and you will need a pump and holding tank...
