    Finished SLAM! Next Step?

    So I have successfully finished my first SLAM! So excited I discovered this website and TFtest kit just prior to my incident of having topsoil dumped in my pool! The water is now sparkling and I passed my OCLT last night! Yay!!!!

    My next concern is adjusting my SWG and also lowering my TA.

    6:30 AM results
    FC 14
    CC 0
    CYA 50-60 ( I have standard solution on order, still learning this test)
    pH 7.8
    CH 225

    After passing the OCLT I adjusted my salt level and turned the SWG back on. It's set at 30% (down from the 40% I have kept it on the past 2 years with no problem) and this evening at 6 PM my FC is at 13.

    Should I turn it down further to let the FC drop?

    Is my FC low enough that my pH is registering accurately?

    Congrats on completing the SLAM!

    Your pH will not test correctly while your FC is above 10. Your TA will drop on its own as you add acid to adjust your pH. Just keep a close eye on your pH when you get below 10 FC because it will likely rise quickly until your TA gets under control.

    You can just shut down your SWG for a day or two to let your FC drop to the target. You will want to bring your CYA up to help decrease the amount of FC loss during the day, but you can wait until you get your standard solution and are more sure of your current CYA. From there just figure out your run time and % through trial and error.
