    Opeining Pool - Green Swamp - How many bottles of bleach?

    I'm fairly new to the forum and this is my first post so hope it makes sense. Opened pool two days ago and it was a green swamp. Added some shock (I know, but the CYA was 0) and yesterday added 8 bottle 96 oz bottles of bleach 6% chlorine. Water is now light green and you can see some of the bottom in the shallow end. We did vac the pool bottom & sides.

    How many bottles of bleach do I need to add to knock the rest of the algae out? Pool specs below:

    35,000 gal
    Inground vinyl

    Any and all suggestions will be greatly appreciated. I love this website and have learned so much!

    Assuming your cya is in the middle of the range (40), your suggested shock level is 15ppm (according to the pool calculator). to get to shock level you would need 11 bottles. if you had a green swamp, as you say, then most (if not all) the chlorine you added was already depleated when you woke up the next morning. my suggestion is to read the "turn your green swamp into a sparkling oasis" article on this site and get a good test kit recommended by this site.

    There's no way to tell how much it will take in advance. A lot depends on how gooey the water is, how much stuff you scoop and vacuum out beforehand, and how diligent you are about replenishing the bleach to keep it at shock level. Here's one success story:

    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Thanks so much! The 11 bottles is a starting place. We have brushed the sides and vac'd the bottom, how thorough it was is difficult to tell as we couldn't see anything. I started to read the article you mentioned and was interrupted will go back and finish. I'll keep you posted.

    We cannot help you calculate the # of bottles/gallons of bleach/liquid chlorine without knowing what your CYA level is. So, the very first thing we need to know is a full set of test results. Also tell us how you got them, pool store, test kit (which one), etc. This is what we need:

    FC
    CC
    pH
    TA
    CH
    CYA

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
