Hoping to get some insight here. I have a brand new pool that is about 40 days old. It is 13,500 gallons. This past Monday, the builder came out and put in (4) 40 lbs bags of salt. His instructions were to check the salinity (button C) tomorrow and add the necessary amount until I get between 3.0 and 3.5 gpl. Here is what I did:
On Tuesday morning => It read 2.3 gpl, so I added (1) 40 lbs bags of salt. I checked that evening and it read 2.7
On Wednesday morning => It read 2.7 gpl, so I added (3/4) 40 lbs bags of salt. I checked at lunch and it read 3.2. I checked at dinner and it read 3.2. I checked at around 7pm and it read 3.2
This Morning => It read 3.1 gpl, so I did not add any salt. I came home at lunch today and read HH with code 145. This code states I am over 4.0
How can this be?? I did have to shock the pool last night....not sure if this is a factor. I will take a sample to be tested at a store to see what the salt level is at, but wanted to get some advise here.
P.S. - I have, and have had, the chlorine production set to 0%
