Leave TA alone for now. I still think the cloudiness was from your CH add. (Assuming you don't have nascent algae). It is best to add calcium with low pH, like 7.2-ish. With your plaster pool, you want a CH at 250+.

Also, remember you can use a 10ml water sample for FC/CC and multiply your drop count by 0.5, (or divide by 2), to save on reagents.
