    Darn. Do I have to shock again?

    I finished shocking our pool, FC tested nine on tues. Was letting it level down. I took a break for a couple days because I was just tired of it and overwhelmed.

    Dumb excuse I know but a big move with two little ones will do that to ya.

    Anyway. Tested today, so I could figure out how to start with out SWG. Currently it isn't running or has no salt. My numbers were good. FC was 1.5

    We have some black algae that didn't go away during the shock, but we weren't really scrubbing. We vaccumed it all up but it's back, water is clear though.

    My results are pH 7.2
    Hardness 250
    CYA- still less than twenty. Should the dot be completely disappeared or just not black?? We added five lbs during shock
    Alkalinity 80
    CC .5

    restart the slam if you see growth. It will be faster than last time. Make sure you scrub every inch of the pool, behind stairs, inside of stairs, etc...

    how long ago was the CYA added? if can take a week for it to show up on tests...the black dot should disappear. (I dislike that test as it's very subjective...and I'm anal retentive....it's the best test out for CYA that I know of so it is what it is.)

    Make sure you don't drop below the SLAM FC (for a CYA level appropriate to the amount of CYA you added) until you pass the three SLAM criteria.
    1. CC .5 or less
    2. pass OCLT
    3. clean clear water.

    you must pass all three.

    Okay, CYA finished adding on the 18th. We will slam again. Last time I didn't scrub the whole pool
