Do you know what your daily consumption of Alkalinity is? What you need to do is get your Alkalinity up to a comfortable zone then stop dosing it. Each day at the same time of day test your Alkalinity. It will drop..... do this for a few days to see what your daily consumption is. Then you'll need to dose your system back up to where you want it. No more than 1dkh per 24 hour period when bringing it back up. Then you'll turn your doser back on and see if you are meeting the demand. If it's still falling then you need to increase your dosing pump to match the consumption. If it rises then you'll need to turn down your pump and dose less. [emoji4]
What you want to do is get that Alkalinity stable first. Then you'll end up matching your dosing according to that.
It looks like you may have overdosed the elements to start. So I would completely concentrate on your Alkalinity. The calcium will naturally fall. You need to get that Alk dialed in first. [emoji4]
