I tested my FC and found it to be 3 but my Total Chlorine is high meaning my Combined Chlorine is high? I used my Basic Kit for a Total Chlorine reading and found it to be dark yellow. I also noticed the "chlorine smell" a few nights before...
I figure my Combined Chlorine is the culpret so I shocked last night with two 1 pound bags of Sodium Hypochlorite (the pool is 8700 gallons) and let the pump run until morning. I tested the water again this morning and the Total Chlorine is still that dark yellow color.
Here are the numbers:
Total Chlorine = dark yellow
CH = 250
I am not sure what is going on and why I am getting / keep getting the dark yellow readings on my total Chlorine.
Thank you in advance..
