    My 2nd year on the TPF method

    Last year I discovered this site and it was the best thing for my pool. I opened pool this year and it was a little green and cloudy. My numbers are


    Ph 7.6
    Ta 90
    Cal 80
    CYA 50
    FC 6.0

    I've been testing FC everyday and trying to keep it around 6.0. I usually lose about 1.0 FC/day

    It has been opened and is getting better, but I want to make sure my numbers look good

    Did you SLAM when you saw the green?

    No I didn't, as soon as I got the FC level up the green cleared up. Should I always SLAM when I see any green?

    I'm not the expert, but I would. I would imagine in your case it would have been only a day or two.

    As a rule, it's best, but if you elevated the FC for a time and it was very minor, it might be fine. Sometimes, a short period of elevated FC can do the trick, sometimes not. If it comes back when you start keeping normal FC levels, then you'll know you should have done a SLAM procedure. Often in cases like this, you can do a SLAM and it will be a very short and easy one. Being your second season, you likely have a pretty good handle on things by now, so see how it goes.

    Thanks for the advice. The water looks good today, but just not crystal clear yet. I'm hoping it just needs more time. Do the rest of my tested levels look ok?

    An overnight chlorine loss test should give you a pretty good idea whether or not any algae is left.
