We have a 6 month old pool that has a auto pilot nano salt system.
when the system was first started and was set a 50% it would keep the chlorine level at 7.5 free.
we reduced the level to 25% and it dropped to 4.0 free. During that time we added muratic acid to keep ph levels in check. The need for acid slowed till is leveled off at about 48 oz a week.
then we lost our chlorine level and had to add chlorine to keep a free level of at least 3.5.
i contacted the pool contractor and was told to check the phosphate and nitrate levels.
we had a phosphate level of 975 which we treated with phosfree and now have a 0 phosphate level.
we still are not producing enough chlorine to keep a level without adding liquid chlorine.
our water chemistry has been even this whole time with not changes.
pool contractor sent out a service company and they checked the system and said it is working. I did see chlorine gas come off the element when it was in a bucket. They said it is a problem with the water. So I took a sample to their store without telling them who the service company was and explained my problem and they said it is a bad system as my water tests just fine. Not sure what to do at this point. Below is the current water chemistry.
fc 0.5
tc 0.28
ph 7.4
hardness 250
alkalinity 100
cya 66
nitrate 10
phosphate 0
salt 3000
system set at 95% but currently on boost system runs 7 hours a day
have not had to add acid in 6 weeks since issue started
volts 15.5 amps 5.5 amp hours 3200
just added 128 oz of liquid chlorine to get a free level of 6.0
pool is 10,000 gallons
pebble tec finish
solar cover is on
phosphates were from city water supply none added since phosphate treatment
I am about to give up on the salt system because no one can give me an answer
thank you in advance for your help
