Water is crystal clear. Was staying pretty well balanced but chlorine dropped during day in sun but we typically brought it back up each evening. Last night the CC level was 1 and ph jumped to 8.2. Already put muratic acid in and ph back to 7.5. CC before was always 0 or .5. Should I be concerned that it went up to 1?
1 CC should I be concerned?

An elevated CC does not mean the worse, but it is a clue that your pool is struggling. For now, increase your FC through this evening based on your CYA. Use the Chlorine/CYA Chart (link below) to help you. Whatever your target FC should be, increase it by 2-3 ppm for tonight. Consider doing an overnight (OCLT) as well. You might squeak-by without requiring a SLAM tomorrow. Only time and the OCLT will tell.
Did you have a lot of swimmers yesterday? That'll drive up CC and lower FC faster than normal. A lot of splashers will also aerate and drive up pH.
We been swimming a little bit each day. Extra kid here or there but no huge groups. Lost 1 part chlorine overnight
