As a grandfather of twins I totally understand. I'm retired and have nothing but time to kill.
I'm not too sure how well auto testing and auto dosing for alkalinity is going these days. IIRC
@VintageReefer did have an auto kalk test and dose set up on his system. Perhaps he will stop by and share his method.
You can automate alkalinity with a KH Guardian for 400$ it will test every 4 hours and determine how much sodium bicarbonate solution to add. If the tank doesn’t need any, it skips dosing. Lots of safety features in the software to prevent overdose, and good modern hardware tech - optical drip count sensors, magnetic stirrer, etc.
No App! Can access from web browser on any WiFi device if you get a WiFi bridge for 25$. Has built in onboard dc jack to power the wifi bridge so you don’t use an extra outlet.
Reagent is $20 and lasts 2 month when testing 6x a day/night.
