    Warming Texas water and chemistry

    Ran the full test today after maintaining FC and pH throughout the colder months. Seems like everything is pretty much in line but water has a slight slimy feel that I haven't noticed before. Water is warming to 69 and SWG has started producing again. Salt is down to 2650 ppm with a goal of 3400.

    FC 1
    CC 0
    TC 1
    TA 50
    CH 240
    CYA 60

    Any thoughts other than what The Pool Calculator suggests would be welcomed.

    Re: Warming Texas water and chemistry

    The main thing is that your FC level is too low. With CYA at 60 and a SWG you want to keep FC between 3 and 5, and never below 3.

    I recommend keeping TA between 60 and 70. As it is the start of the swim season, it is good to raise CH up to at least 300, so it will last the season (unless you have high CH fill water, which has very different care). Same thing with CYA & salt, raise to the higher end of the normal range so it will still be reasonable later in the season.
