Did you have to lower ph and raise ta?
My ph taylor readings drop from over 8 to under 7 with one drop of 05 and my ta reads 20 from tap.?

Adjust alkalinity to 80-120ppm prior to adjusing your pH.

A 20ppm alk reading will draw your pH very low which in turn is very hard on your skin as well as extremely corrosive to your heater element.

Just use baking soda?
