bnhorner Posted July 12, 2014 Report Share Posted July 12, 2014 My Aquapure 1400 is not generating chlorine. I have no error codes and the "cell on" and "flow" lights are on so one would think that it is generating chlorine. I have the chlorine production set to run 10 hours a day at 90% due to the high temperatures in Texas. My water chemistry was out of whack but I'm working on getting it back in the recommended ranges. The pH is at 8.6, the total alkalinity is as 250 ppm, and the calcium hardness is really low at 80 ppm so I've added the recommended amount of MA and Calcium Hardness (recommended by retail pool store). My salinity is at 3500 ppm so it's right on the border line. I have the new 3 port salt cell which was replaced in November 2012. It worked perfectly fine last year, or so I thought, and now the only way I can keep chlorine in my pool is with weekly shock and chlorine pucks. Could the sensor have gone bad or is the water chemistry to blame? Any feedback would be GREATLY appreciated. Thanks in Advance! Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted July 16, 2014 Report Share Posted July 16, 2014 What is the chlorine stabilizer level? Quote Link to comment Share on other sites More sharing options...

chem geek Posted July 19, 2014 Report Share Posted July 19, 2014 The Jandy Aquapure 1400 should output 1.25 pounds (567 grams) of chlorine per 24 hours so at 90% on-time over 10 hours that's (10/24)*0.9*567 = 213 grams of chlorine. Most pools having a chlorine level sufficient to prevent algae growth use around 2 ppm (mg/L) per day so this 213 grams would support 213,000/2 = 106,500 liters which is 28,134 gallons. So unless your pool is nearly that large, then you have excessive chlorine demand most likely caused by nascent algae growth. In a saltwater chlorine generator (SWCG) pool, you need to maintain a Free Chlorine (FC) level that is at least 5% of the Cyanuric Acid (CYA) level. Also, if your pH is super high as yours was, then that reduces the active chlorine level as well (though with CYA in the water it's not reduced as much -- even so, 8.6 compared to 7.5 reduces the active chlorine level by around 20%. You need to raise your chlorine level to shock level (around 26 ppm with your 65 ppm CYA) using chlorinating liquid or bleach and maintain it until you kill off all the algae and have <= 1 ppm overnight chlorine loss (i.e. not in sunlight).

bnhorner Posted July 26, 2014 Author Report Share Posted July 26, 2014 We ordered a new sensor. Worked fine for a week. Got the pool chemistry correct. My pool is crystal clear. Walked past the board to see it stuck on "wait" and won't switch to "flow". Getting error codes 172/190. Is it a connection issue with the board? The salinity still reads correctly when we press the button. Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted July 28, 2014 Report Share Posted July 28, 2014 What did the new sensor look like? Was it grey with white epoxy or grey with black epoxy? Quote Link to comment Share on other sites More sharing options...
bnhorner Posted July 28, 2014 Author Report Share Posted July 28, 2014 We have the grey with black epoxy. We realized that the "jumper" on the adapter was in a plastic bag rather than on the adapter. We added that to the adapter because we don't have the firmware that says it's not needed. Everything seemed to be working fine as the flow and cell lights were on. This morning though, it's back to the "wait" and "cell reversing" and the flow light is not on and the salinity reading is --. This is a NEVER ending battle with this thing. I took a water sample to the pool store and was told the chlorine was at a 1 so it's working part of the time and acting up the rest of the time. Any solutions for this now? Thanks for all your help.

Pool Clown Posted July 31, 2014 Report Share Posted July 31, 2014 After you installed the jumper, did you recalibrate? Quote Link to comment Share on other sites More sharing options...
