Hello All. Had my pool re plastered in the first part of May. At that time I decided to use a pool service to keep up my chemicals. Turns out they use pucks and liquid chlorine. Only being serviced once a week I started keeping track of CL and PH and saw wild swings in both during the week. I got rid of the pool service a week ago and will be doing my own service from now on using the TFP method. Got a TF100 kit and took some readings today:
According to the CYA/Chlorine chart, my CL target should be a little under 5. The manual for my brand new Raypac 407A states that the CL level should not exceed 5 or damage could result to the heater.
Given this, what should my target CL be? I do not have a SWG.
