I just tested my pool and got these results.
16000 Gal
FC-4
TC-5
PH-7.2
ALK-140
CAL-210
CYA-20
Pool temp is 83
Should I be concerned with the low CYA reading?
What are the acceptable ranges for the readings?
Thanks

Your numbers actually look pretty good, except that FC + CC = TC, so if your FC reallyis 4 and tc really is 5, then you have 1 ppm of cc, which means you need to shock your pool.
What kind of pool? Vinyl, gunite, etc? Depending on what kind of pool and if you have heater/SWC/etc, the guidelines could change, but a good basic range of chems is pH 7.2-7.8, alk 80-120, calcium doesn't matter if your pool is vinyl, but needs to be 200-400 in gunite/plaster pool, CYA is a personal choice. You don't need to be concerned with the low CYA reading IF you're able to keep chlorine in your pool throughout the day, and IF you're diligent about testing/chlorinating your pool. If you find that the Cl is being consumed too quickly during the day (that's after you shock it and get rid of the cc), then you might want to consider upping the CYA a little. Most people recommend somewhere in the 20-40 ppm range, there are a few of us that intentionally run higher CYA pools.
