2 part users - how often do you NEED to adjust 2 part dosing program/timer to get the steady parameter?

Every 4-6 months or so, but when I do need to adjust it I usually have to adjust it a few times over the course of a couple weeks until I find where it needs to be at again

I test levels once a month and then dose accordingly. Whenever I make a change in dosing levels, I typically wait a week and test again to make sure it's perfect. I've been using a dosing unit from china. Works really well too.

After my dosers got dialed in correctly, I started testing monthly and am always stable.

While I was setting up my dosers, I tested daily for 2 weeks

I was dosing manually but it was a pain. Dosers were one of the best investments I made in my tank. Now, with no daily work, I can test any time of day, any day of the week, and alk is always 9.2 or 9.3.

When I add several frags, I retest every few days to see if consumption increased and I add a few minutes as necessary

I test my water parameters once a week and adjust my peri pumps accordingly.

I check alk weekly, normally everything is in line but I'd say every couple months I'm adding on some time to the dosing pumps. Really the answer to your question is highly variable and dependent on your exact system, I'd start with weekly tests once things are dialed in and go from there.
