    Convesion step 8 CC going up?

    My pool is crystal clear have been following the steps up till step 8. Now I'm confused... when shouls the CC be zero in the morning when you first test? Also, as my fc goes down durinv the day (hot and sunny) my CC is going up. 2 hours after I raised FC to 15 it came back to 9 and Cc was 2.5 is this normal?

    The goal is zero CC in the morning. But until the conversion is complete, wildly swinging CC levels are normal. And using a lot of bleach is also normal.

    Thanks. I thought I was almosr done. I was holding fc over night and my cc was down to 1 before I changed out the sand. I did start getting lazy with adding the bleach ( 2-3) times a day. I will get back on top of it and see how it does. Thanks again

    Re: Convesion step 8 CC going up?

    Let me understand.....

    1. FC lose overnight is less than 1
    2. Water is clear
    3. CC is around 2.5
    4. You have added CYA to around 30

    Are these all correct??

    Have you tried an OCLT?
    Did you add stabilizer?

    Leebo,
    Sorry if I wasn't clear on my last post. Yes to all 4 of your questions. OCLT is the overnght chlorine loss test right? I used Haas conditioner which is cya only.

    Re: Convesion step 8 CC going up?

    Ok.....just wanted to make 100% sure here. If your CC level is now 2.5 then it shows somewhere there's still Baqua. Keep shocking at a 15FC level. With CYA in the water the chlorine should hold better than before, but may still need topped off. Make sure you are scrubbing a TON. Every crack gets scrubbed. The spots by the steps, returns, skimmers, drains, and lights are all very common hiding spots. If you have an inground pool with light you may even want to remove the light and scrub in there. That garbage is hiding somewhere, but will go away. Ton of vacuuming helps out too.

    Thanks for the advice I will start scrubbing more and vacum more. When you talk about vacuming often is that like a once a day or even more than that?

    Re: Convesion step 8 CC going up?

    I didn't get out as early as I should have but at 7:15am my FC was 13 and my CC was 3 so I lost 2ppm overnight. My family is getting frustrated with me since I thought we were almost done. It seems worse after I changed the sand in the filter. Also my cya still reads zero after I added as a slurry yesterday. So do I just keep adding bleach? I don't know where else the cc is coming from bu it definately worse since its been hot the last two days. Thanks again.

    Re: Convesion step 8 CC going up?

    Everything you describe is normal. After you add CYA things fluctuate a little. This is because the CYA greatly slows down the activity level of the chlorine. You are quite near the end, but it could still be several days.

    The CYA test can't measure anything under 20. It can take CYA up to a week to fully dissolve and show up on the test, so it is best to simply wait a week after the CYA addition before testing CYA again. In the meantime you can behave as if the CYA is present, even if the test says otherwise.

    Thanks Jason. The family is going crazy not being able to swim! We are having our first really good weather of the summer and everyone just looks at the crystal clear water and wants to get in. Almost there!

    Kept the FC @ 15 checking every hour today. Just checked for the last time for the night and FC was 16 CC was 2. We will see how it goes in the morning. Thanks again to everyone for the advice.

    Assuming you are following the article for the Shock Process in Pool School, that is exactly what it tells you to do.

    Others will disagree but I don't see a problem with you swimming as long as you keep your FC at the correct level.

    Re: Convesion step 8 CC going up?

    Thanks for the feedback Dave. Can you clarify what you mean by the correct level of FC? Do you mean the 15ppm that the conversion process requires?

    Yes, he does. FC shock level as dictated by your CYA level.

    Re: Convesion step 8 CC going up?

    I added the amount of CYA the pool calculator told me to add on Saturday the 29th as a slurry. On Sunday it still read 0. I didn't check my CYA this morning but Jason had told me to act like the CYA is present. I'm not sure if that advice holds true in this situation.

    So it might be ok to swim with the levels as they are currently? As the sun burns some of the FC down below 10 would it be ok for the teenagers to swim for a short time? Or are the CC's too high at 2.5

    Thanks

    Re: Convesion step 8 CC going up?

    CYA takes a while to be completely dissolved and then thoroughly mixed in. Even if you added it as a slurry you need to wait a minimum of a few days before re-testing it. I really don't know what level of CC is irritating, but the FC levels you mention are fine. I know we have been in a good deal more FC with no ill effects.
