Cannot chorinate

[sinkin]

When I got home last night & rechecked the chlorine it was once again at zero. I then added 2 gallons of 12.5% shock & approx 91ozs (1/2 of 1.42 GAL) of 6% bleach. This brought the chlorine reading back well over the 5ppm limit on my tester (probably around 12). I did not have time to buy distilled water last night to do the diluted X 2 test but will buy some tonight.

I then re-tested at about 10:00PM and the chlorine level dropped to about 5ppm. I then added 2 more gallons of 12.5 shock. This morning at 6:30AM the chlorine level was still at 5ppm! Yippee!! This is the first time in 1-1/2 weeks that I had a chlorine reading in the AM!

My wife just re-checked at 9:30 this morning and the Chlorine is still at 3.6ppm. I didn't have her add anything but asked her to re-check at around noon & let me know.

Thank you Watermom!! I think I finally see some light at the end of the tunnel.

What chlorine level should I strive for? should I still be superchlorinating to 12PPM?

Prior to posting here for the first time yesterday, I was in the process of changing out my water. Monday evening my CYA was at 30 as I was pumping out & refilling water after starting out at 100. When I rechecked the CYA last nite after a few more hours of water changing yesterday AM, the CYA was something < 30 (which is the lowest limit on my cheap tester) so I am not surprised that the chlorine is diminishing. I don't want to add any stablizer until I receive the K2006 tester that I ordered yesterday.

What is the recommended CYA reading? I'm cautious to add any as I had a previous bad experience with too much in the past after I was "pool-stored".

Thanks again for all of your help.

I'd go ahead and keep the cl up for another day just for added insurance and to make sure you don't still have the large cl demand. Then, with CYA of 30, you can keep your chlorine level between 3-6ppm and you'll do fine.

Glad its going well and ...... you're welcome. Glad to be able to help!
