I am having a hard time with my test strips reading total chlorine. My free chlorine read 1-3 and total reads 10+ (dark green). I tried shocking and it just stays at 10. I use diclor about 1/2 tsp per person after use. I've shocked first with MPS and that is when the reading shot up and shocked two days later with diclor. I dosen't make sense that there would be a 9-7 combined chlorine (clorimines) with free clorine still available . ???

A typical shock will not oxidize 7+ PPM of chloramines. I would recommend at least a double if not triple shock, leave the cover off for a couple of hours if you are oxidizing with cl/br in this case.
As for your other question, yes you could still have free chlorine with 10+PPM of chloramines.
