Your chlorine level won't stay at 6 or 7 for long. Until that CYA dissolves and starts to register on your test, the sun will deplete your chlorine pretty fast. Make sure for the first few days, you test and add some chlorine several times a day -- morning and evening. Once your CYA is in there, you'll be able to test and dose in the evenings only.

Wait on your kit to tweak TA. Go swim!!!
