You're fine. Glad you got your FC up from zero! One of the things I was going to suggest because of that zero reading, was to do an overnight test. You take it to shock level (15ppm) around dusk. Then test a half hour after that addition and record your FC/CC. Then, the next morning test as early as you can, definitely before direct sun hits the pool, and compare your FC/CC. You are golden if your FC loss <1 and your CC is 0.5 or less as the third criterion for the overnight test is that your water is clear. You already have that! (As an aside, if I do the overnight test, I do it one more night just to make absolutely sure).

Then we can talk about raising that TA. Next time you are going to the store, pick up a box of Arm and Hammer WASHING soda (not baking soda). It's in the laundry aisle.
