For those who automate alk testing- do you let your controller adjust alkalinity, or just observe for trends and dose equally over 24/7? I have an X10 on one of my systems, and a Kamoer KH Carer on another. The more I test and observe the dosing amounts adjusted, the more I want to pull back from letting the controller adjust the alk amount dosed, and just test 2 times a day and observe upward/downward trends… seems like a lot is on the line when relying on something like a hobby grade PH , but I could be alone here…
