Float Switch needed - DIY ATO

[Snaz]

Thanks. I bought the ebay ones above and it ended up costing ~$4.50 each. Your offer is a great deal. I built my ATO and took pics but I haven't had the time yet to make a DIY post. It was the best upgrade I have done so far for this tank.

do you need a vertical or horizontal float switch to make it work?

I used the vertical ones as pictured in the Ebay link. It sits in my back compartment and is working a treat. This last week my little 12 gallon tank is going through about 0.75 gallons a day of fresh water as I blow across the surface with fans to keep it cool.
