If you are trying to get an accurate picture of what you are using, you MUST use the FAS/DPD test. The drop tests are for a balanced pool doing daily sanity checks.Drop test. swg off. My thoughts, if it is only putting 5 chlorine how is it supposed to keep it at 6?
If you don't think your cell is producing any/enough chlorine call either Jandy or your builder.Water test today
oclt last night less than 1 pump and swg off for overnight for test.
Pump set for 35 gpm, swg 100% for 13 hrs. 1700 rpm
Took water sample to pool shop ( friends run it I use tfp plan) to verify readings. All almost identical . They said FC was 5 my tests said 10.
