    Question First test results

    Hi,

    I just received my TFT test kit. I am new to having a pool and look forward to all I can learn from you folks and hope to contribute someday. Ok, first results:

    FC=1
    CC=0
    TC=1
    PH=7.4
    TA=120
    CH=150
    CYA=98
    TEMP=58 degrees

    I just recently got rid of a small algae bloom. How does this look?

    Thanks in advance!

    Welcome Bonnie. Looks like you are in for a partial drain/refill with that high CYA. It's truly your first step. You will use way to much chlorine just to get the minimum FC level, let alone SLAM'img levels! Have you been using pucks?
    I'd bet you my bikini you'll never get TFP water from a pool store!

    Yes, I have been using pucks. How much would I need to drain? (dang...)

    First test results

    If you use Pool Math it will tell you how much water to replace to lower CYA X amount. Just plug your numbers in the now and what your target CYA level you want to reach. Don't forget to add your pool water volume at the top.
    Also if you could add all your pool and equipment info to your sig that will help us better help you. 😎

    The pucks caught up with you just like they always do. At least now you know. If you have any left, save the for vacation.

    Thank you!!! I am going to retest CYA one more time (I did more reading on the test process) and will start dumping and refilling per the pool math calculation.

    Re: First test results

    New test results for 5/12 5:29 pm

    FC=.55
    CC=0
    TC=.55
    TA=100
    CYA=70 (didn't replace enough water)
    CH=150
    PH=7.5

    So, using the pool math calculator:
    I should add bleach and borax/soda ash/washing soda

    Is that correct? If so, do I do one before the other? Or do I need to do something completely different?

    Thanks!

    Re: First test results

    .55? What test are you using?

    Your PH and TA are fine so you don't need anything except chlorine...

    How does your water look? That would determine if you need to lower the CYA more or if you can get by with that level for the rest of the season. Backwashing with your sand filter the level will slowly drop over the summer.

    Re: First test results

    Well I would suggest then that you do an OCLT and determine if your FC is holding overnight. If it is, you don't need to SLAM and you can try and run with the CYA at 70. You just need to be diligent and keep the FC above the "Min" at all times - no cheating. LOL

    My first summer on TFP 7 years ago I lowered my CYA from 140 to 70 and ran it there the rest of the summer. Was fine.
