    New Pool Update

    I have almost been up and running for two weeks. My most recent test all have been looking good.

    CYA 50 to 60 Was hard for me to judge not seeing black dot.
    TA 90
    PH 7.6
    CC .5

    Here is my question My chlorine was at 6.5 as of this morning and as of tonight after a sunny 90 degree day it was at 1.0. Is that not a big drop in one day? That means 100 oz of bleach a day. Should I up stabilizer more or see how this goes. I was expecting 20 to 40 oz per day average.

    Your CYA is already at the upper end of the recommended range. That FC loss is more than you would get from just the sun. I would suggest raising the FC and doing the OCLT.

    Tested my FC last night at it and this morning and there was .5 drop and as of tonight 5.5 drop. It is in full sun from 10 to 5. I am running filter 24/7 on low. Could that be part to blame?

    Re: New Pool Update

    Chlorine is only lost to organics and the sun. You appeared to pass the OCLT, so I am wondering if your CYA is not a good bit lower than you think. Or a bunch of people/animals peed in your pool today

    No one has been in the pool yet. Exactly how is the Taylor CYA test to be read. It was cloudy but I could still see the black dot some at 50 but not much

    You need to do the test outside in bright indirect light with the tube at your waist. Pour it back and forth a few times to see what you get.

    One thing I'll add, is be careful that you're not seeing the reflection of your head looking down into the tube, and mistaking it for the black dot! I've done that a few times. lol

    Re: New Pool Update

    I am going to try and retest this evening or tomorrow on the CYA. I am thinking that maybe it was me not reading it properly. I did only add 3lbs in trying to be careful of not going to high. If my pool is in direct sun for as longs as 7 to 8 hours what would be the recommended level? Would it be a bit higher for that reason? And lastly what is a normal drop of FC per day in this setting?

    Re: New Pool Update

    We would recommend your CYA to be around 50ppm if you have a lot of sunlight ... which is where your current test indicates, but your FC loss is contradictory.

    Typically pools loose 2-3ppm of FC each day.
