constant drip with salt water??

I have heard of people doing this. Techincally, it can definitely work. 2 dosing pumps is all it would take. 1 drop in, 1 drop out. The problem being that these pumps need to be extremely precise or it will cause too much water or not enough water in your tank. You definitely wouldn't want 1 to fail and 1 to remain on.

As for ATO, it will have no effect as your ATO replaces evaporated water. I wonder if you could end up with ALK issues though as a lot of salts have higher ALK amounts. So you would be replacing the current stabilized alk levels with higher alk levels everyday. I don't know if this would even be an issue but something to consider when trying to stabilize your water conditions.
