It's all safe. Most eyes don't care with any 7.My target pH is 7.4? Whatever is safe on the eyes!
Now that you're back on bleach, the Ph will rise once you bump the TA. Maintain a high 7 Ph instead of a low 7 Ph and both Ph and TA will likely find their own happy place.
I haven't touched either all season, and I only adjusted Ph once last year.
