The reason you want to drip it into your tank is that you want to limit the pH swing you'd get by dumping a large uncontrolled amount of kalk into the tank. But if you're using an ATO, you can just have kalk powder directly into your reservoir and a little powerhead to mix it up, because (presumably) the ATO is already topping up your tank in small increments over the course of a day.
You can use an IV dripper, or even just a water jug with an irrigation needle valve somehow.. whatever you can set up will work. So long as the drip rate doesn't exceed the evaporation rate you can more or less set it to whatever you want. Start slow and increase as needed (without exceeding the evap rate) - e.g., if you find your levels are dropping then increase the drip rate, wait a few days and test again.
Finding a steady rate can be a challenge.
I use a DIY kalk reactor (mixer) using a dosing pump feed a steady slow drip rate and a powerhead on a timer to mix the kalk/water. I just add more kalk than is needed so to get a supersaturated solution and top up the power once per week, and maybe take the whole thing apart for rinsing and cleaning about maybe once per month.

I would really like to see pics of your diy kalk drip..
sounds like a great system.
