I get my fc up to 6 at night and next morning its still six maybe 5.5 but by noon its down to 2 i bring it back up to 6 and by 4 pm its down to 2 again. is this normal or should i raise the cya. Also this is my first year starting with bbb after finishing the last 30 days of the last season, never has it opened this easy and the water clear up this fast, thanks to all

    Yep, looks like you need to up your CYA to maybe around 50ish.

    Is your pool in full sun?

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: is cya my problem

    i have 3 inch triclor tabs left from last year, what do you think about using them to get the cya up seeing how my ta is high. thought the tabs would raise cya and lower the ta. if so how many would i need to go from a cya of 30 to 50

    It would be a slower process to raise the CYA this way. You can use the PoolCalculator.Com to calculate the amount needed to do what you want.

    I for one would use the tablets since you already have them. It's not like you have to be in a hurry raising the CYA or lowering the TA. Or are you???
