    Just got my TF-100 XL

    So I have been struggling with my pool all summer. It is not clear and is turning green. I run the filter constantly and have been fracking it ever week. I ordered the TF-100 and want to start enjoying my pool So let's go. Here are my results.

    FC 29
    CC 1
    TC 31
    CH 150
    TA 120
    CYA 65

    I can't see the bottom of the deep end. It is cloudy. It was turning green 2 days ago so I shocked it. Maybe to much as my chlorine readings are through the roof.

    Where do I start?

    Hi,
    you wont regret the Test Kit. It along with pool math will be your best friends.

    If I were you, before I started teh SLAM, I would let the FC drift down to below 10.
    Then backwash the filter and record teh pressure reading. This will be your "Clean" pressure.
    Next, if your pH is high, then adjust it down to 7.2.
    Then start the SLAM.

    Here are the SLAM instructions. Make yourself intimate with them. Getting rid of algae by any method is a process. There isnt a magic cure. It will take days or more to get rid of it and get your pool crystal clear.
    Pool School - SLAM - Shock Level And Maintain

    The important part, is teh MAINTAIN the shock level FC. That level will be relative to your CYA.
    The more vigilant you are about mainting the FC at shock level, the quicker it will go.
    It would be easier on you if your CYA were lower which would reqire drain and refill half the water, but you can do it at 65. It will take twice the amount of chlorine.

    Here is the FC/CYA chart.
    Pool School - Chlorine / CYA Chart
    Use only liquid bleach as your source of chlorine. No powder shocks because they add other stuff the pool which you do not need. Especially with your CYA at 65

    Use pool math to determine how much liquid chlorine (a.k.a. bleach), to add in order to maintain the required SLAM (shock) FC.

    You will need to brush all of the pool surfaces daily. Algae will will stick to the walls and grow biofilm over it to try and protect itself. Brushing will destroy it and let the chlorine kill the algae quicker.

    Also, not a bad idea to take out your pool light. Algae likes to grow in the light niche and will drive you crazy. Its worth the effort.

    You will need to run your pump and filter 24/7. When your filter pressure rises 20-25 percent above "clean" pressure, then it's time to backwash it.

    You've already started.

    Shock level for 65 (call it 70) CYA is 28. You're there. Get in there and brush the walls and vacuum blindly and recheck the FC level again in a couple hours and raise it back up to 28. Keep an eye on the filter pressure and let it run all night. Check Fc again in the morning before work and raise it again. If things look iffy with the filter pressure, turn the multiport to recirculate when you're asleep or at work.

    Yup. Agreed here. Just do the SLAM as long as your FC is already there!

    Re: Just got my TF-100 XL

    Thanks everyone. I have family coming this weekend in 3 days. . Can I still slam or should I hold off and let them enjoy a cloudy pool?

    You can still slam. Its safe to swim all the way to SLAM level FC.. which in your case is 28.
