Tunze Osmolator.....A bit expensive but worth it IMO. I can take 1/2 cup out of my sump and it replenishes immediately. My sump level stays within probably 1/4 inch of the desired level...probably less than that.
I have this one and like it pretty well so far. I'll be replacing it when I get my controller if I can't wire it in somehow.
You could set up a 50ml doser on a timer or use a controller... just have to figure out how much evaporates in a day. You can also add a float switch to cut the power if it somehow over fills.

I also going to be exploring the one that AvastMarine offers but not sure what pump to use with it yet. I'm having trouble with my current setup on my quarantine tank where the water doesn't stop and it adds more water than I want it to add.
I'm using an aqualifter pump from a 10g tank behind the wall of my tank. I drew a line on the sump where the water level is and have looked at the tank probably a hundred times today. Right before the ATO kicked on, I was looking and it had barely moved below the line, about 1/16th of an inch. I'm very pleased with the performance of my float switches. here's what it looks like in my sump-

Is that a good thing?

Probably what mine is doing...I need to take a look...I'm using an AquaLifter to top off. I even tried swapping to my other Aqualifter but it still continued.
I've noticed that the aqualifter will siphon when off. My reservoir is a 10g sitting on the floor, and the tubing to my sump is above the water line, so the only option is to siphon whats in the line back to the reservoir. Have you tried moving the pump up higher than the water level of the reservoir?

With the aqualifter, the end of the output hose must be higher than the top water level in the top off container...
Run the output of the 1/4" line up high and have the output end empty into a 1/2" hose that is just above the sump level..

I just use a Kent float valve tied directly into my RO unit. I did it like that for many years then I worried about the float valve failing so I added an electric valve in line before the float valve in the sump so there are two things that have to work together to add water. If one fails the other will stop an overflow.
I'm a cheap-skate.... 50 gallon reservoir in another room with a 1/4" line going through the wall to a float valve in my sump.... hasn't let me down yet

I set my aqua lifter up like this last night so we'll see if that fixes my issue. Thanks for the idea.

Another thing I setup for using a float valve is to set a minimum time for the pump to be on so it didn't fill it just barely only to have it cycle quickly. I told it minimum on time for the pump was 2 min so I'd fill it a tad above to give it time before it needed to top off again.
