    first slam

    getting ready for my first SLAM. I believe I have a pretty good idea on the process but I would appreciate any tips or comments that might help. Here are my pool readings using the TF 100 test kit.

    Re: first slam

    First, familiarize yourself with the Chlorine CYA Chart which will give you the target FC SLAM level (24 ppm) for your CYA of 60.

    Is there any way you can come home for lunch to test/dose FC? That would be best. If not, then I would consider getting up a little earlier than normal and test/dose FC followed by another round of FC testing/dosing as late as possible before leaving for work, assuming the time between these is at least one hour. Then, focus the remainder of your testing and FC dosing in the evening. I would test/dose as soon as you get home and then again before you go to bed.

    A good test kit is an investment, not an expense.

    Re: first slam

    Bo and I are basically saying thet same thing, I just got beat to it.

    Sometimes life gets in the way, but you have to do the best you can. Do you have any type of automatic chlorinating system?

    Assuming you don't and since you're gone during the day, I'd raise the FC to shock level right before you leave for work and then test and raise it back as soon as you can and then every hour until bed time. That's not ideal, but we have to do what we have to do. It make a day or so longer than it normally would, but it will work.

    Re: first slam

    sounds good. I used the pool calculator and got 18 for the shock level, am I missing something? I am hoping that it will be a fairly short process. There is no signs of any visible algae in the pool. Actually it looks better using BBB than it ever has with the exeption of using too much chlorine you wouldnt suspect a problem but I know there is. I do have a chlorine generater but I have not been using it .

    Assuming it's an swg, if you have the salt level correct, I'd say turn it on and let it run during the day when you're gone.

    Re: first slam

    its not a swg its for the puck type chlorine. Should I fill it and use the pucks during the SLAM process? I just have had issues with my CYA being too high so I dont use anything to chlorinate except bleach.

    No. This will add CYA and you want CYA to be steady during SLAM. Stick with bleach.

    Re: first slam

    Well, the midday dose would only added to help the chlorine level a little bit while you can't tend it. You're levels will drop quickly early in the slam process. Wait til day 2 of your SLAM, and depending on loss from day 1 you should be able to make a guess as to what would be a safe amount to add. Any at all is good!

    Re: first slam

    It's just a difference in the way the number was derived. Either will work and be safe, but the 24 ppm may get the job done a little faster.

    Also, if you can teach your friend/neighbor to test, and to use pool cause, that would be even better!

    Re: first slam

    I started my SLAM last night unfortunately I tested again right before and my CYA levels are 80 instead of 60. (Done it outside). SO here was my test results when I started
    CYA 80
    PH 7.5
    TA 200
    CH 300
    FC 1
    CC 1
    Also the pool has no visible signs of algae and is clear. I added 6 gallons of 10% bleach at 6:15 tested at 7:45 and got a FC of 38 ( a bit high for shock should have been 31) and a CC of 2. This morning I tested at 5:48 am and had FC of 14 and CC of 1.Added 2 gallons of bleach have not tested yet waiting 1 hour. I fell below shock level overnight, does this mean I have to start over? Also as I stated earlier in my post I do work and it may be a problem to add or test every 2 hours. One question I have is I just want to make sure that I am not damaging my pool or equipment by adding so much bleach. I feel that I should actually go a bit above my shock level so that it doesnt fall below when Im gone. Is this not a good idea? Does it seem like I am on the right track here??? Sure would appreciate any help.
