Your PH is a little low, nothing to worry about but it might be a good time to bring it up a little. Aeration would be a good way to bring your PH up, or borax if you want.
Your chlroine readings seems inconsistant. If chlorine means total chlorine, total chlorine can't be 3 at the same time that free chlorine is 10, it is impossible. If chlorine means combined chlorine then 3 is a very high level of combined chlorine that is suggestive of a major algae outbreak and you need to keep shocking. Hard to tell without more information. Before your chlorine and free chlorine readings were always the same, which suggests that chlorine is total chlorine.
Other than that your numbers look reasonable.
