Chlorine Lock ????

Ok, update: I purchased an Ammonia test kit with the drops and color card , goes from 0-8ppm. I will do it as soon as I get home and test the FCL and TCL again.

Ok, the reults are in :
On the Lamotte kit, FCL is .41
TCL is 1.45
On the FAS-DPD kit it turned a tinge pink when the dpd powder was put in, then 1 drop of R-0871 cleared it up , which should indicate .5 FCL , then 5 drops of R-0003 turned it pink , then 2 drops of 0871 turned it clear which should indicate 1.0 of CC , I don't know if that means we are coming closer to solving this, I did put in the 10 pounds of Calcium hypo into the skimmers at 10:30 am before leaving to a meeting , and the pool is cloudy due to the chemicals. I did these CL tests at 4:45pm, the Ammonia test came out with 0.25 ppm (mg/L) so I don't think ammonia is the problem. There is no visible algae, no alge on the floor. I'm going crazy .....Should I use 8 gallons of 6% bleach overnight ???

Did you measure that FC tonight? Did all the Cal-Hypo dissolve (that's why it's cloudy--don't worry about THAT for now)?

If so, it's now evening, then add 5 gallons of LC...I think you are fighting the organic, whatever it is. Check your FAS-DPD test in the morning, too--BEFORE you add more. If it's come up, you are making progress. But you'll need to add enough LC to get it to the shock level.

PATIENCE!
