    Then you will have to keep your FC up about 9-12 ppm and your SLAM value approaches 40 ppm.

    Please read the SLAM article. I think that is what's next.

    Did you use the dilution method for your CYA test? If not, see #9 here: Pool School - CYA

    Thanks everyone. Went ahead and threw 20oz of 73% hypo in with a good brush to bring up to slam level.

    I did not use the dilution method yet, will try that tomorrow morning.

    73% calcium hypochlorite? I would use plain bleach instead- your CH is already high at 300 and you said drain is not an option. For your pool volume (20k?) that 20 oz addition raised your FC by 5 ppm to 8 ppm which is still below even maintenance level recommended above let alone SLAM.

    It's all I have at the moment. How much bleach would I need to put in tomorrow morning?

    depends where your FC will be at that moment. You can use PoolMath link at the top to estimate how much. As an example I entered 20K for pool volume and it says 1 gal of 8.25% bleach will bring FC up by about 4.5 ppm.

    Looks like I can get my hands on a pump tomorrow or Sunday. Should I go ahead and bring it to slam levels today? Then drain half tomorrow or Sunday and go from there? Or just wait and drain/refill and go from there?


    Also, we've had quite a bit of rain lately. Is it safe to drain half? Or can I drain on one end and fill from the other for say 12 hours and achieve the same effect without actually lowering the water level?


    Thanks for all the input!

    Probably best to drain first as to not waste chemicals and $$ on bleach. Yes, you can add water from one end while draining from the other, but it's not as efficient. Sometimes though, it's your only option when you only have one skimmer and no main drain. But having a pump to use should help quite a bit. Confirm that CYA first following the water exchange then start your SLAM for best results. Good luck!

    Thanks Splash.

    I just tried the diluted method for the CYA and got 118, so it's definitely high. Also checked my FC again and it's up to 12 since I added shock and what bleach I had on hand last night(obviously not high enough for slam level). I'll wait to pump some water out then bring to slam levels. QUESTION: What can I expect the CYA to be after a 50% water replacement? And do I use the corresponding slam level of the CYA reading AFTER the water replacement? In other words, if my reading after water replacement is 60, then bring it to 24, correct?

    Also -anyone know what the solution is in the TF 100 kit for testing CYA? My bottle leaked and I only have enough for probably 2 more tests as I go through this process. Can I get that solution locally?

    It's melamine but I don't know of any application other than pools (although I am sure there are some) Taylor sells it as R-0013 Many pool stores should have it in stock.

    Re: Help Please - Numbers posted

    Just wanted to post an update and new #'s. On Saturday I replaced 50% of my water and started the SLAM process. Numbers below. My PH is high, but pool school tells me PH is inaccurate during SLAM, when should it be accurate again? I know my SLAM FC is high for my CYA (I got a little carried away with the bleach). I plan to do the OCLT tonight.

    FC - 34
    CC - 0
    TC - 34
    CH 275
    TA - 120
    PH: 8.2+
    CYA - 55-60

    Not sure why noone answered you but the ph test is unreliable once you exceed 10 FC. Thats why we adjust the ph before we start the slam

    How is your slam going?

    Thanks Caco. It's going well, looks like I'm in the clear. Losing less than 1ppm over night and water is clear as can be. Letting it drift down to normal chlorine levels now. My PH was good pre slam so should be good there. Going to need a refill on my solutions after all this testing!
