Its all flow and bubbles, and most of us who have tuned these things over a decade do it by feel.
And your not alone, we all learned to set flow like that the hard way, less those wanting to be more precise buying a pump. What you will do is adjust your bubbles not by ph but by how much your tanks needs are.
Check it in 3 days and if alk is on the high side just cut bubble count lower until you hit your sweet spot
