Mary,
You will find that TFP ideal levels & pool store ideal levels often conflict for various reasons like, the motivation to sell you products (tfp sells nothing), along with following antiquated industry standards.
Use our tool to find ideal chemical levels for any swimming pool. Check TFP recommended levels on pH, free chlorine, cyanuric acid, and more.

Your ph of 7.2 is a little low but requires no intervention, With a ta of 80 your ph will likely rise on it’s own.
Your chlorine level is not high, in fact it is right around target
for your cya if that is all free chlorine
FC/CYA Levels.
Fc anywhere between minimum & slam level for your cya is fine & safe for people, equipment, & surfaces. Most here opt to run fc around high target or a scootch higher to allow for some cushion incase of higher bather load, equipment failure or other environmental factors.
One issue here is that you listed the total chlorine (tc) measurement which is the sum of fc (good stuff) + cc (bad stuff).
You need a proper test kit with an fas/dpd test to measure the two individually so you can be certain of your actual free chlorine level as cc’s (combined chlorine) over .5ppm warrants intervention.
All of the recommended kits-
(taylor k2006(c) salt or tf100/pro salt) contain this test as well as all the tests you need to properly & accurately test your own water, which is recommended over relying on the pool store
