    SLAM- Chlorine question

    I have been learning from the site and love all of the information! I am starting to SLAM.
    I just got my Taylor k-2006 yesterday.
    PH 7.4
    TA 20
    CYA 35
    Before adding bleach (10% sodium Hypochlorite from Atwoods)

    According to the Pool Math I needed to add 1 gallon+ 3quarts+ 2 cups bleach
    We have a 21x52 above ground vinyl. According to a calculator it holds MAX 11,300 gallons, I used this amount for SLAM/chlorine purpose.

    CYA/Chlorine chart said I needed 16ppm (I rounded CYA to 40) to SLAM

    Problem: I added correct amount (1 gallon and 3+quarts) measured my Chlorine with kit and it only showed a level of 10ppm. ( I used 20 drops of regent 0871 before it turned clear, using the 10 mL sample. (20 x.5 = 10ppm)). We are opening the pool so it is green. I know there are CC's.

    Is this the correct amount of chlorine or do I need to add more?

    Welcome to TFP!

    You should raise the TA to at least 60 as soon as practical.

    A green pool consumes chlorine rapidly. It is hardly surprising that FC didn't get as high as you intended, some of it got used up right away. That is what happens when you are fighting algae. You want to test the FC level, and raise the FC level back to shock level as often as practical, as often as hourly (especially on the first day) to get ahead of the algae.

    Re: SLAM- Chlorine question

    Could I raise the TA while adding chlorine today (using baking soda)? I was afraid of raising the PH too much. I will add 2 more gallons of chlorine.
    Should I backwash before adding? I didn't want to lose any chlorine, but I want to keep sand filter as clean as possible.

    Thanks so much. I have already drained 2/3 (CYA was 100 from a year of pucks), refilled pool, lowered PH from somewhere above 8. This site has walked me through it all!

    Re: SLAM- Chlorine question

    Greetings Sleding! Probably goes without saying, but ..... yep .....start stocking-up on that bleach/liquid shock! You're going to use it. Also, when you get a moment, you might consider adding a signature to your profile with all of your pool info for easy reference later. It helps TFP folks evaluate your situation quickly and more accurately. See my signature or JasonLions in this thread as examples. Best of luck!

    Call the local hardware stores to see if you can get 5 gallon jugs of liquid chlorine if you want to save a few bucks. I get 5 gallons of 12.5 percent for under 14 dollars.

    Yes, you can raise the TA while other things are going on.

    Welcome to TFP! These guys will get you straightened out if you listen to them!
    25,000 gallon IG with vinyl liner. Not sure how old it is. Sand filter, not sure what brand/size, Hayward Super Pump c48k2n143b1. I have a Polaris 180 cleaner on it's last wheel (haha). I'm still not sure about water restrictions, but haven't gotten any hate mail about the amt I used last summer. I absolutely LOVE my TF-100 test kit.

    Welcome to TFP! The best way to post pics is upload them to photobucket then copy the IMG code and paste it here.

    Re: SLAM- Chlorine question

    Make sure you're vacuuming or using the leaf rake/bag to clean the bottom. Even if you can't see. You want to get as much gunk out as possible. I found a pile of it in the middle of my pool almost a week into the slam, after vacuuming and raking a LOT!

    ***update**

    20 gallons of bleach, 2 weeks (3 days out of town ), about 10 inches of rain and a whole lot of testing...later..

    Still needs a little clearing, keeping chlorine up until 'crystal'. Wanting to get DE, but have not been anywhere to get some.

    No CCs <.5 as of yesterday

    Re: SLAM- Chlorine question

    ** update**

    Got the idea of panty hose from this site.
    After 2 days of using old panty hose, the pool looks amazing !!!

    I cannot believe the amount of stuff they were catching: tiny bugs, loads of hair ( my 2 girls have waist length), fuzz, and some small white particles (dead algae I assume).

    Trying to upload a pic, but not able to now. Thanks for all the help.
