My Tank Thread
I was worried about that too when I switched but I just set it to dose throughout the day and let it do its thing. I check with my Hanna once a week after a daytime test runs and it’s close. The controlled dosing is set for 8 and doesn’t seem to try to overcompensate when the tests at night have some dips in alkalinity. The midnight test is nearly all of those dips, some are the 6am test.
How does it know to stop dosing AFR? Is it set to a naturally slow dowsing rate or short times??
