With sodium hypochlorite as your primary source of chlorine, I would suspect that a TA of 60 would probably work for you. However, I would suggest the rule I posted above. Try a TA of 60 ppm and a ph of 7.6 to 7.7 and adjust the TA based on whether the pH rises or remains stable.
Also, a 3 ppm limit on the fc is pretty low. That does not give you much room. I would suggest staying as close to 3 as possible and keep the cya closer to 30.
Yes I agree about cya and chlorine but what happened is I got injured and the boss put tablets with conditioner in chlorinator so there is the problem with that but splashing water out of the pool is going to take care of that. The problem with aeration is that I can't say really how bad ph is acting and the only way to tell is from the quantities of acid that I have to add to adjust
