I'm looking for some recommendations for which test result I should trust. Pool details are in my signature.
Salt level per Hayward panel - 2500ppm
Salt level per Taylor drop test - 4000ppm
Salt level per Test strip - 2600ppm
The pool is new and has been filled for 2 months where salt levels have decreased from 3200ppm to where it is above. No significant water replacement other than backwashing.
My cell is reading low salt and I'm planning to add 30 lbs to bring it back up to ~3000ppm per pool math (11,500 gallon pool). I am a bit concerned that the drop test is so much different than the others?? I've tested salt weekly and its always significantly higher than the cell and strip reading.
Should I proceed as planned or test salt another way?
