    After the Slam

    Okay, I have got the pool stable after SLAMing, as follows:

    PH: 7.5
    FC: 27.5
    CC: 0.0
    CH: 250
    TA: 80
    CYA: 70
    Borates: 40
    Salt: 3200

    From what I've read, and the Pool Calculator, I do nothing at this point. Is that correct? I just wait for the FC to fall on it's own? Do I leave the SWG off until FC gets into a more normal range? Should I still be testing daily if it passed the overnight test? Or can I go back to a weely routine?

    On the one hand, I feel empowered having completed my first "go round" self-testing and SLAMing. But, that FC number is a little scary.

    Thanks,

    Let the FC fall normally. You should still test FC every day until the it comes down to single digits. Then you should turn on the SWG and start determining your cell output % versus pump run time in order to keep your FC at the recommended level for you CYA. Once you get your FC to hold at 3-5 FC using only your SWG, then you can go to testing only with your K-1000 color comparison TC and pH testing. But even that should be done daily until you're very comfortable with things, then at least every other day. You worked hard to get the pool clear, no sense not investing 10 minutes a day (usually less) to make sure your chemistry is good. Then I'd still do FC/CC and TA every week with drop based testing.

    Thank you. It's coming down very slowly, which I guess is a good thing.
