Chlorine Lock ?

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.

I am going to start a whole new testing round today so I have current, hopefully correct, numbers. It's a very rainy, hot day here in SC and when my #1 son gets home (and if it is not pouring) we will start from scratch and log the numbers on the guide provided by Pool Doc last night. This pool is not going to get the best of me!
Thanks to all for continued guidance.

Some testing tips for you... If you're unsure of the CYA reading / result, you can retest with the same sample. Just pour what you got into the test tube back into the little dispensing bottle with the remaining leftover sample, shake, and then pour it back into the test tube for another look. No need to use more reagent for another test. Also, it is best to look down the tube in outdoor daylight with the sun at your back. Lastly, the pH reading will be artificially high due to the high amount of FC you have. So, don't let that surprise you.

Good evening. I did the full testing tonight and have posted on the guide PoolDoc gave me. My numbers are terrible-especially the CYA of 130. I tested with the diluted test using distilled water and pool water.
Other numbers:
25.6 ppm FC6
3.6 ppm CC
7.4 PH
150 TA

Feeling pretty bad that all this effort is not producing results. I'm ready to drain my pool...

Dont feel bad. Consider this all a learning experience that'll only help you later on. It figures your CYA was higher than the prior reading of 80.

If you want to drain, you'll need to do it in steps so you don't damage the liner. Drain leaving no less than about a foot of water at the most shallow end if your pool. Refill, retest, and redo if need be.

I'm sorry things have been so frustrating.

1. Hang on a little longer. Enter daily test results in the pool history spread sheet. Do NOT test CYA -- it's not going to change, and you'll run out of reagent.

2. Complete the equipment form: http://pool9.net/pf-equip-form/ Try to include your pump and filter models. Once you've got several days results posted, and have have the equipment form completed, I'll go back and re-read this thread from the beginning and see if I can make more sense of things.

3. Keep in mind that draining a vinyl pool is a HUGE issue, and can destroy your liner if done incorrectly.
