    Newbie has question about chlorine

    Hi. We recently drained and refilled our IG 22000g guinite pool. This is my first year to follow the TFP method and it has been great! In fact things are going to good which has me worried that maybe it really isn't correct . 4 days ago I added a gallon and a half of bleach, added baking soda, stabilizer in a sock and then the next day Borax. My numbers have been good except for CH (very low) and I just bought some to add. CYA is a tad low but from what I have read it takes about a week to kick in. My main concern/ question is my chlorine level today (3 days since adding bleach) is still 4. Which is my target level. But shouldn't I be having to add chlorine daily? Or is it possible that because my pool is is shade most of the day it just isn't being burned up? My pool is crystal clear and looks great but it seems to good to be true. Lol.
    In ground Guinite pool 22,000g. Hayward filter system, using Taylor K-2006 for testing, totally new to this whole pool thing. Located in Tennessee.

    assuming it was 8.25 bleach you added
    1.5 gallons would give you 4.6ppm fc
    as it is fresh fill and shade and water is still cold,
    it is possible you haven't lost any fc yet
    but i would suspect it was a higher strength you added

    Sounds like you're one of the few who's pool is in a very efficient stage right now based on position, sun, etc, that FC simply isn't being consumed as quickly as other pools in the country. If you've been comfortable with the Taylor kit for some time now, I'm assuming your readings should be accurate. Any idea how old the reagent(s) are?

    However to be safe, you're welcome to post a full set of numbers for us to compare - just in case.

    Re: Newbie has question about chlorine

    It was 8.25% bleach that I added. And the Taylor k 2006 kit I am using I just purchased and the agents don't expire till late 2016. I appreciate your comments. I guess I am just shocked how well my pool has turned out without having to spend big $$$$ like I usually spend at the pool store. I am so glad I found this site and for all the information and input! Thanks

    Re: Newbie has question about chlorine

    According to poolmath my target CYA is 40. 2 days ago when I checked it it was 35. How often should I be checking my numbers and should I add some more stabilizer? My sock is empty. I just added it 5 days ago.

    Give it time. 35 is within the window of error for 40. With low,FC consumption there is no need to worry about adding more jut to reach a magic number.

    Re: Newbie has question about chlorine

    With a 'target" level of 4ppm of Fc-----you have a whopping cushion of 1 to be at your minimum FC level for your CYA. I'd sure keep a close eye on it.
