Can I do an ATO for a tank only setup? Or do I have to have a sump? I have a 29 gallon with a HOB skimmer.

Please be really, really careful trying to find an ATO for "as cheap as possible". They're going to fail on you at some point. Check out the new-ish smaller Tunze Osmolator Nano. These work great with very little worry of failing, and cost under $100. That's cheap for protecting any saltwater aquarium, particularly a reef tank.
