    Exclamation 1st SLAM!

    I am newbie to the TFP method.... Just opened my pool on Friday 5/8 and started the SLAM procedure,As of this am my CC is down to 1.
    I had no idea it would take sooo much bleach to do a SLAM.
    I think in all i used around 27 gallons of 8.25% to get to the CC of 1 and FC of 8 this am.
    Is this normal?I wasn't prepared for that amount ...

    Welcome. This is very normal. Just keep SLAMing. Can you post a full set of numbers for us please?
    Your FC is low for Slam level shock.

    25,000 gallons is a pretty good-sized pool. That amount of bleach actually sounds a bit low. I sure hope you disconnected the Nature2 and the puck feeder, or at least have them empty.

    Yes I stopped using tablets and took out the nature2 mineral cartridge. I also put 10,000 gallons of new water in to bring my CYA down to 40.

    Re: 1st SLAM!

    Looks like you need to bring it up to 16 according to the calculator: http://www.troublefreepool.com/calc.html

    Also FYI if you are using Great Value concentrated bleach from Walmart it says 8.25% but if you read further the actual yield is 7.85% available chlorine. I am not 100% but that is the # I use when I calculate.

    Re: 1st SLAM!

    I think I used 24 gallons on my pool, I remember someone saying 2 bleach gallons every 1,000 gallons of water when I was slamming, was a "rough" estimate.

    Welcome to TFP! No need for a rough estimate, use PoolMath to calculate exactly much to add.

    Here are some intro Pool School articles to read while you wait for your test kit
    TFPC for Beginners
    ABC's of Pool Water Chemistry

    Here are the Recommended Levels for your pool.

    Re: 1st SLAM!

    Ok got home from work and check my FC3.5 and cc-1.0 figured out how much to add to bring back up to 16 for slam. Add that amount now 2-hrs later FC is .05 at best. This am when I left for work it was FC-8 and Cc 1.0 added the appropriate amount to bring up to 16ppm.

    Re: 1st SLAM!

    This is normal especially in the beginning. Just keep adding bleach to reach your targeted FC of 16. The more you can test the better.

    Re: 1st SLAM!

    I guess I didn't realize I was going to be using $40+ per day of bleach.

    Can't you achieve the same thing by using non-chlorine shock to destroy the chloramines?

    The bleach use will slow as you progress. Add more bleach to get your FC back up there.

    Re: 1st SLAM!

    So let me ask another question .... After I am finished withe the slam process how often would you need to slam again? Or is it just maintain your daily loss of chlorine?

    Quite possibly, never again. Certainly not during the swim season. Just maintain FC above the minimum for your CYA and it can;t get started. If you close your pool late and open it early when the water is too cold for algae, you might never see algae again.

    Re: 1st SLAM!

    My family is starting to doubt me...especially since I opened the pool and with 10,000 of fresh water it was just cloudy. No swamp
    Or anything like that. As of now is is just a little cloudy. And I am still dumping Clorox in like I have stock in the company. I keep telling them to trust me.

    Show them some of the SLAM threads and testimonials so they can see it works. The link to my SLAM is in my signature.

    I am glad you believe in it and they will too when you show them how your pool looks in the end.

    Re: 1st SLAM!

    LOL, get off the bleach! When your SLAM is complete you normally only need to add 2-4ppm per day to maintain FC level. The key to not having to SLAM your pool again is to never let your FC drop below the minimum for your CYA level here, Chlorine CYA Chart. Keep it at target or slightly above. Also, it is safe to swim as long as FC is below shock level.
