I believe there are also some other @chemgeek posts which show that low TA is desirable in an SWCG in order to minimize calcium scaling as the local environment inside the cell is so alkaline that the CSI is very positive relative to the bulk pool water. Also borates help to reduce scaling inside the cell as well because calcium borate does not or can not form.
You might give borates a try someday
after you get bored with solving the world's problems 
I was quite impressed with the changes to my pool water chemistry. Plus, it adds a little extra algae-death insurance to the water.
