Chlorine Locked?

Add bleach to 15 ppm and report your test results.

Looks like you are gaining on it. Stay the course!

Hi Reesie - I just saw your post to my thread and I find it so interesting that we both used the CDX system ( as well as those oxidizer tablets) these last few years - even more evidence that the CDX is playing a role in why our conversions are not going as planned.

Every time I think I am gaining on my pool, it backfires. For example, I had a day when my FC was 5 and CC was 0.5 - and then the next morning it was 4 and 1. When I then added bleach ( to keep my FC high like is recommended) my FC only raised to 5 but my CC went to 6! It has happened again today. Very discouraging.

I read on another forum one person who said it took 2 months to convert. And I would rather not wait that long.

I have ordered the sodium percarbonate and will try it in a 2 gallon or so bucket at the recommendation of chem geek before I put it in the pool. At the same time, I am making preparations to do a drain and refill. This is a really busy week for me with work so nothing will happen quickly, but feel free to follow along on my posts - I will certainly let you know if I have any significant luck with the percarbonate! Hopefully your conversion continues to move in the right direction. aciam

I added 4 gallons bleach last night. I didn't get a chance to test until 1:00 pm today. It's not very sunny today.
OTO results:
fcl >5
tcl >5

Taylor:
fcl 15
tcl 15
ccl 0
ph 7.4
alk 140
cya 50
Another interesting note: We had a thunderstorm that knocked the current off. My husband went out to the pool to turn the pump back on and decided to take the cover off of the filter before he turned everything back on. Now, we just changed the sand on 5/29/2011 at the pool store's recommendation. The water has been completely clear since around 5/15/2011. There has not been any debris or algae anywhere in the pool. When my husband opened the filter, there was a bunch of gunk in the filter. Baqua-poop?
So, what next?
Change the sand, let the chlorine levels drop and swim?
or am I being too optimistic?

Here I go again. Just for curiosity I took a sample to the pool store (around 5:00 pm) and checked it again myself around 8:30 pm with the Taylor kit. We had another thunderstorm with heavy downpours. The readings changed a lot from this afternoon.
fcl 5 (pool store 3.8)
tcl 10 (pool store 9.8)
ccl 5 (pool store told me I didn't have any combined chlorine)
alk 140 (140)
cya 50 (40)
ph 7.4 (7.4)

Where do I go now? I was hoping I was through with the combined chlorine...especially when I still didn't have any at 1:00 pm this afternoon after adding the bleach last night.
or did the rain have anything to do with that?

[Watermom]

Stay the course for one more day and see if the CC is still no more than 0.5.

On 6/16/2011( Thurs.) I added 3 more gallons bleach to bring it above 15 ppm fcl around 9:00 pm.
Tested noon on 6/17/2011 (Fri.)
fcl 10
tcl 15
ccl
5

6:00pm
fcl 7.5
tcl 15
ccl 7.5
I didn't have any more bleach, all local stores were out! even checked the next town. They were out too. No shipments due until Sat. or Mon. They weren't sure which.
I put 3lbs. non chlorine shock in at 8:30 pm.
I bought calcium hypochlorite (65%) today since we are having a hard time finding bleach. I never knew there was a shortage of bleach!
I'm leaning towards draining and filling since nothing else seems to be working. The town water authority is not going to be happy.
We came home from work yesterday and found that our pump had burnt up so we had to buy a new pump. It doesn't appear to be our year!

6/18/2011
I tested:
Taylor kit: pool store:
10:00 am 12:00 noon
fcl 7.5 0.5
tcl 10 7.0
ccl 2.5 6.5
ph 7.2 7.2
alk 120 120
cya 30 20
th 120

I don't know what to do now? It doesn't seem to be getting better. The combined chlorine is not 25 like it was (if that reading was correct) but it's still not going away.
