This is about exactly where I was yesterday.. 2600ppm. I added 120 lbs salt to bring it up to 3400ppm, which is a little bit on the low end of the range. My pool guy says he cleaned the cell when he was out last Monday (3/27/17) and that he reset the controller so that it shouldn't be flashing right now. I just sent him a text, as he comes out today, asking him if he reset it last week and he said he did but it takes a day or so to stabilize. It is a week later now and still flashing plus he didn't salt the pool last week saying he wanted to let it run after cleaning before adding salt to see if it comes up. REALLY? The cell is in no way going to change the salt level in the pool, is it?
Also, in his response today he said he likes to add salt slowly (whatever that means) and that the read out on the AquaRite is often wrong so he's bringing out an "independent salt tester".. Shouldn't he be bringing that every week or at least once a month?
I've been reading the TFT pages on chemical testing and I have a $10 off coupon for TFTestKits from signing up to this site. I used to maintain my dad's pool back in the day and know how to do it. I'm about ready to fire this guy TODAY because I see on my newly installed security cams that he's there about 10 minutes a week and charges my $105 a month PLUS $70 to clean the filters 3 to 4 times a year and another $50 to clean the salt cell 4 times a year. I've cleaned DE filters before and it isn't that difficult to do, just a little bit of a PITA and takes a couple of hours of my time. I see that cleaning the salt cell is not very hard either. I've been paying him for the convenience but lately it seems that I have to intervene way too much and it really isn't all that convenient..
Anyway, does the digital readout report erroneous salt concentration? I really can't see it being off by more than 100ppm, the accuracy of the readout, but could I be wrong?
Is there any other reason a freshly cleaned salt cell would be flashing the "Check Cell" LED other than the controller not being reset after cleaning it? This answer seems very suspect to me.
TIA
