    Lab results,clear water.

    Hi,

    Just offering up my lab results for critique:

    FC=.5
    CC=.5
    TC= 1
    CYA=20
    Salt=3200
    PH=7.8

    I know I need to raise my CYA and my Chlorine, feel free to let me know how.


    Thanks

    Raising CYA is easy. You just buy some stabilizer, pour it in a hole-less sock and tie it off and set it in the skimmer, or dangle it in front of a return or tie it off on something that floats. The sock in the skimmer is less work.




    To raise the FC fast, get some bleach in there before algae gets a toehold.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Richard, every time I see that second pic I laugh a little inside. Ever see a product called truck nutz?

    When you say lab tested, what do you mean? If you had to send the water away for analysis I would not trust the FC/CC/TC readings to be accurate. Too much time between sampling and testing. If you meant lab in the pool store, well I dont need to say more... If you have direct access to a local lab though then I assume your readings are good to go!
