    hazy green water

    ok, I've been doing BBB for a few years now, thanks to the help of this board. I though I had a good handle on it but I am stumped! my pool has been a hazy green for a few days now. at first I thought algae <uggh> and shocked it into submission. when the levels were high enough and there was still a hint of green I put together 2+2 with my friends little ones having an "accident" in the pool maybe?!? so shocked it some more and it mostly cleared up...this is day four at shock levels...slowly letting the tc level drop because it should be good by now--but I come home from work tonight and bam..its hazy greenish sorta again. not full blown green, just sorta drifting in that color direction. other things are out of whack now too--ph is high, ta is high..they were great and in range 3-4 days ago. what's going on? can this really be from someone POSSIBLY peeing in the pool (I don't even know if it actually happen, but I don't usually have little little kids in it and recently did--so it's possible)

    help please

    Review the article on how to perform the shock process in Pool School. You need to hold it at shock level until you pass the 3 tests to stop ... not just because your gut tells you it should be good.

    Post up a full set of tests ... specifically the CYA level.

    Also remember the pH test is inaccurate when the FC is > 10ppm.

    What he said: all 3 tests have to pass

    CC is 0.5 or lower;
    An overnight FC loss test shows a loss of 1.0 ppm or less;
    And the water is clear.

    If you shortcut, the algae may regroup and counterattack, and all the bleach you poured in was for nothing.
