Chlorine Lock ?

Yikes! Pool experts, I believe I have screwed up my pool even worse! Received new bottle of reagent this afternoon and tested tonight. My numbers...FC 36, CC 7. I kept putting bleach in morning and night for the past 3 days hoping I would keep up the progress we were making in the numbers. I far surpassed the 25ppm I was shooting for. And went way up in CC also. Pool is not quite as clear as it was a few days ago and saw some algae on bottom-not a lot. Looking for some guidance please. Did the supposed chlorine lock break and,even worse, did I keep adding when I should not have.? I starting to freak out again!

In a complicated situation like yours, it's hard to track the changes unless you record and present them systematically.

If you would please us the form, http://pool9.net/pf-hist-form/ to enter your observations. Feel free to post earlier observations if you have retained them.

Let me know when you have a couple of records up, and I'll take a look.

One more thing: if you have done so, please watch the testkit videos completely; they are linked off the test kit page => http://pool9.net/tk/

We have kept a record of testing FC and CC since the first round of complete testing for everything when I got the official k2006 test kit. I did post those numbers. We did have to stop for a few days when we ran out of FAS-DPD and had to order. Tonight was the first test since Mon.-am.

Also...watched, watched and re-watched all the videos when doing the complete line of testing.

It's odd that CC is so high with all that bleach in there. You might want go ahead and double check your CYA test using the diluted sample mentioned earlier. In other words... if the CYA is truely at 80 it'll read 40 with a 50/50 sample of pool water and distilled water. You'll notice the testing tube is easier to read the differences in amounts at around 40 than at 80 due to the graduated scale of the test tube readings.
