This seems to be a pretty reasonable way to make an ATO. Cheap and already put together. Some mods would need to be done, but it looks totally possible. Or I could just be mildly retarded.
Alot of parts in the toilet bowl aren't made for salt. Really, for the price of ATO of where they are at. I feel more comfortable buying it..ATO is something you don't want to go cheap on or cut corners. Hate to come back to a tank full of Fresh water or burnt out pump.
