    Should I raise my CYA?

    I feel that my CYA is on the low side. My SWG info recommends 60-80 for CYA. Should I raise it? My FC is holding at 3, day and night. And also, my PH is a tad high. It is between 7.5-7.8. Here are my numbers.

    FC 3
    CC 0
    TA 70 (SWG recommends 80-120)
    CYA 55
    PH 7.5-7.8 (SWG recommends 7.2-7.6)
    SALT 3400

    And I must comment about my son-in-law calling a 'pool guy' to give him advice on his pool. I think the 'pool guy' might have him convinced not to install a SWG or to use BBB for his pool! Boy when I get back down to Florida on Sunday, I am going to do this to my son-in-law !

    Raising the CYA to between 70 and 80 will make the SWG last longer and help you chemistry be more stable.

    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.
