Working on getting the DW to test and add chlorine during the day (while the pump is on ... since I am not home while it is on). Dipped down to FC of 2.5ppm (CYA of 45ppm) a few times in the last few weeks. Noticed we were losing a good 4ppm each day which seemed excessive to me, but the water looks great.
So Saturday, I backwashed the filter, lowered the pH a bit, made sure all the suction and returns lines were open and started the shock process:
3:30PM: FC 3.0 ... added 1 bottle of Walmart 8.25% bleach (should add 4.5 ppm ... and did)
6PM: FC 7.5 ... added 2 gallons of 10% from Lowes (first time using this stuff)
9PM: FC 23.5 ... wha?? should have only raised it by 11 ... must be pretty strong or my testing is off
9AM: FC 16.0, CC 0.5 ... little late for an OCLT, but seemed like a large drop, added 1.5 bottles of the 8%
8PM: FC 8.0, CC 0.5 ... pretty high % loss for the day, apparently should have checked more often, added 2 bottles of 8%
10PM: FC 17.5 ... as expected
6:45AM: FC 15.5, CC 0 ... well failed that OCLT, added 1 bottle 8% to boost above shock level
7:30PM: FC 8, CC 0.5 ... pretty high % loss again, added 2 bottles of 8%
10:30PM: FC 18 ... as expected ... Water looks PERFECT, I mean I do not even see anything floating in front of the light, if the wind was a little more still, it would have been impossible to tell there was water in the pool.
6:45AM: FC 14.5, CC 0.5 ... FAILED again, added 1 gallon 10%
Wife saw me test this morning counting along and then wanted to know why I was adding more chlorine ... I am questioning my sanity as well
The water looks, well it does not look like anything is even in the pool. And yet I am seeing high daily losses and failed OCLT.
I find it hard to believe that my testing could be that far off, but clearly something is not right. I almost wish the pool did not look so good so that I could see what I am apparently fighting
So where does one get the POP
