I have a question regarding the accuracy of the Aquacheck strips for salt. I have a new plaster pool and just recently added the salt and started the swg. I have a aquarite generator and the pool is approximately 16,000 gallons. So according to everything I read I needed to add 440-450#'s of salt initially and thats what I did. The swg has been working great and I have been adjusting it and my run time to keep it at 4ppm. The display shows between 3200 and 3400ppm while its running and a few times 3100ppm. I bought the salt test strips to verify my level and got a reading of 4500ppm on 2 seperate test days! So I am not sure what to do at this point. I was thinking of buying a refractometer to test it or just leave it alone. I dont want to do any damage to the swg or pool. Any suggestions would be greatly appreciated.
