I have had a pool for 15 years and I am having a problem with free chlorine. I have a 23k gallon vinyl pool. Had the water tested at a pool store. My pool will not hold free chlorine. I am told I have chlorine lock and shocking should take care of it. I have shocked it 2 days in a row. The first day with 4 gallons of liquid shock. The second day with 5 gallons of liquid shock. No luck. There is still no free chlorine. I have read that removing the phosphates might do it. Any suggestions?
Total chlorine 1.9
Free chlorine 0.3
pH 7.3
Total alkalinity 110
