We have a 20,000 gallon in-ground salt water pool. We have a Jandy AquaPure 1400 chlorinator and an AquaLink automated system. Earlier this year, we had to replace our filter (no big deal) and then we got the dreaded 172/185 codes and replace the flow sensor. All seemed good as we were back online and no other error codes. In the process of changing out the sensor, my husband looked at the salt cell and saw no visible scaling. We were told to shock the pool several times with di-chlor and add stablilzer and then it should start producing chlorine. We still have no chlorine reading and the water has turned slightly cloudy as a result.
We have shocked the pool about 4 times in the last 10 days, added salt, added stabilizer and calibrated the salinity of the AquaLink system to what the pool sample read. I have questioned doing all of this when our pH and alkalinity is still high.
Like I said, we are getting no codes or service lights to indicate that anything else is wrong with the system. We can see the cell on light, the flow light on, cell reversing and resting lights so we don't think anything else is wrong with the system.
My question is can extremely high alkalinity affect chlorine production? We only have the test strips at home, but the last several times we've taken a pool sample to the local pool store, our alkalinity has been 239, pH above 8.0, stabilizer at 139, total chlorine at .89 and free chlorine at .52. I read online that it the alkalinity gets too high that chlorine production only reaches about 10% of what it should be if that. Could this be our problem or do we need to look at other culprits?
After the last pool sample above (6/3/2011), we were told to add 2 lbs of shock and run the filter but put the chlorinator to 0% for 24 hours then put the system to boost for 24 hours and then back to our normal schedule of 65% production for 10 hours a day. After adding the shock, our test strips read between 1.00 and 3.00 chlorine so I knew something wasn't right.
Can anyone give any suggestions? I am my wits end and don't know what to do.
Thank you for your help.
