    You want to keep the chlorine high (see the Best Guess Chlorine Chart in my signature below for needed levels) until you can go from sundown one evening to within one hour of sunrise the next morning without losing more than 1ppm of FC and your CC level is no higher than 0.5ppm.

    What is your source of fill water?

    Does the liner feel slippery? Have you brushed the pool?

    Welcome to the Pool Forum, by the way!

    Assuming you have no algae (slippery sides mentioned by Watermom = beginning algae), then you need to:

    1. Get your CYA up.
    2. Maintain chlorine levels.
    3. Maintain pH in the 7.0 - 7.4 range.
    4. Decide what to do about your VERY high TA and CH.
    5. Don't worry about the CC levels UNLESS they continue for several days. Make SURE you aren't confusing CC with TC (Total Chlorine = FC + CC).

    You can do a bucket test for CH: http://www.poolforum.com/pf2/showthr...atment-Process

    And, this page will tell you how to lower your alkalinity. But you do NOT want to lower your alkalinity till AFTER you lower your calcium, if you pursue that option: http://www.poolsolutions.com/gd/lowe...p-by-step.html

    Meanwhile, if you have a Sams membership, consider buying a 50# bucket or 24# box of dichlor. Sams is the ONLY big box store I know of that sells undiluted / unblended dichlor.

    The wbsite and forum are both extremely helpful! Thanks for the guidance and resources. I will see what I can do now that I have some direction.

    2. Maintain chlorine levels. Ok.
    3. Maintain pH in the 7.0 - 7.4 range. Ok.
    4. Decide what to do about your VERY high TA and CH. Will read...
    5. Don't worry about the CC levels UNLESS they continue for several days. Make SURE you aren't confusing CC with TC (Total Chlorine = FC + CC). Nope... These were the cc results from the testing. Tc would be 11ppm yesterday and 9.5ppm this morning. I will keep monitoring

    What is your source of fill water? City water

    Does the liner feel slippery? Have you brushed the pool? Brushed over the weekend... Will have to feel for slipperiness tonight.

    Thanks!

    I have 44oz of cya... Do i just follow the procedure here...
    http://www.poolforum.com/pf2/showthr...Way-to-Add-CYA
    All 44 oz at once?

    Also, these are my chlorine levels... Does this make sense?
    5/29
    5pm fc is 6 ppm, cc is 5 ppm
    8pm added 96 oz. 6% bleach
    10pm fc is 5.5
    5/30
    7am fc is 7.5, cc is 2
    7:30pm fc is 2.5, cc is 7.5. Then added 384 oz bleach
    8:30pm fc is 9.5, cc is 5
    5/31
    7am fc is 4.5, cc is 9
    6:30pm fc is4, cc is 10. Then added 384 oz bleach
    10pm fc is 5, cc is 12.5
    6/1
    7am fc is 5, cc is 11
    6pm fc is 14, cc is 5
    Numbers seem to be all over the place.... Not sure what to do now.

    And finally, another question... Sounds like my pump motor is going bad (getting louder, whining noises, and hot to the touch). However, I cannot seem to determine the hp of the motor so I can get a replacement. Hayward Super Pump. Any ideas? Thanks yet again.

    There should be a label on the MOTOR (the hot part). There also should be another label on the pump casing (the part that has water in it). If you can post photos of both labels with Flickr, Photobucket, Webshots, Picasa, or Facebook, we can probably work out what size motor you have.

    I reposted the motor question in the pool equipment section with more details... I did find a model # on the motor (sp2600zlc) but after searching the web, i still cannot determine the hp. If that's still not enough info, i will post photos.
