That page explains how to do -- on purpose -- what you are currently doing accidentally.
Bottom line is, it's not possible to maintain a standard pH level AND standard carbonate alkalinity levels.

Re: Low alkalinity & combined chlorine
I'm not sure why you care about Total alkalinity if your pH is fairly stable. BTW, if you are using pool store "Alkalinity Increaser" you are wasting your money--it is nothing but baking soda, but they label it "Sodium Hydrogen Carbonate" to make you think it is not what it is, which is......Sodium Bicarbonate--baking soda. Sodium Hydrogen Carbonate is an alternate name. You can buy bags of 12-13 lbs at CostCo for about $4....
