my CYA is 40, based on the chart I've been keeping my FC each day at 6 or 7. I've been having a daily drop down to 3 usually. Its a new pool and ive had water in for about 1.5 weeks . My PH is staying at 7.7 or 7.8. TA is a high still, but that's my hard well water. CC is 0. Just wanted to make sure the daily drop of 3 FC is normal.
