can't get chlorine level down!

[pooldog]

having trouble with my chlorine leval,can't get it to come down enough..
6 days ago my reading was about 21 i think with my taylor kit...
drained about,, 1/4 of my pool water and put in fresh..also had a good rain..
added 3-containers of MAJIC JACKS chlorine reducer..which says it should reduce it by,4 each..
test today at pool store they read-11ppm..
my test read 14ppm.....
pool is uncovered and nice and clear..
should not the all of that along with the sun reduced it more??
pump runs 24-7.....

I can think of no reason why you want to force your chlorine down. It will come down on it's own somewhere about 2ppm daily. Why do you feel you have to reduce it?

Man,,you fellows know what you you are talking about.....
I thought 21 chlorine was a ,,,,non swim level,,,
and my cya level was,,50.......

new numbers are,,,chlorine--8
cya --40

now that my chlorine is in the ,,close to acceptable range,,i'll start trying to raise
the rest of my levels,,,then turn my SWG on,,done added salt...
again,,,BIG THANKS guys......... :-D

Those numbers aren't right.

the FC should be 8, not 0. if CL is 8 and FC is 0, your pool should not be clear.

CYA is cyanuric acid, so you can't have a reading of 40 for CYA and 20 for cyanuric acid.

The pH is low. It should be between 7.2-7.6.

You should run those tests again before adding anything else.
