Thread: Starting BBB method (1st results)

    Starting BBB method (1st results)

    Well guys I have had the new pool for 6 months now and kept the pool guy around since I had NO clue what I was doing (and quite frankly this might still be the case). None the less I do feel more comfortable now with taking care of the pool. What really got me started was when I noticed some allege start to stick to the sides...knew right away something wasn't right. From there I broke out my handy dandy TF100 kit that had been setting in the garage for 6 months and completed some test. I don't have the results from that first test, but I do have where I am today and I would like your opinions on where to go from here. I have gotten this far in taking small steps using the BBB method..

    This morning the CL levels were at .5, I added 1 gallon of clorox and now (2 hours later) I am at 3..
    PH = 7.1 (turned on a water feature to agitate the water in hopes of raising a little)
    TA = 80
    CYA = 70
    CH = 230
    CC = 0
    Temp is 84 (hey it's hot in H-Town...)

    Any advice on where to go from here would be great!


    Pool size estimate is 45000 gallons, it is 45 feet long by 15 wide and 10ft in the deep end.

    If you are seeing green, you are going to need to shock.

    Are you running a SWCG? If not, your CYA is a bit too high at 70. With a CYA at 70, the minimum FC you should ever have is 5. 7 should be your target. Your shock level FC is 28. You are going to need to shock, brush, and circulate until the algae is gone, your FC holds overnight, and your CC is 0.5 or less.

    Your pH will come up. Good call on the aeration. It will raise it for you.

    I would caution you on keeping your test kit in the garage. It gets very hot in there and this can be detrimental to the life of your testing reagents. Please keep it indoors.

    Hey, CJ,

    Some questions....

    1. geographic location influences our responses....where is "H-town"

    2. Recheck the size and gallonage of your pool....that's a very unusual shape and the gallonage doesn't work out.

    3. I would leave your pH alone....it'll likely rise on it's own anyway. Use Borax instead of aeration if you still feel the need to raise it.

    4. You are going to need to shock but help us with the questions above first so we can help you with your dosage.

    Re: Starting BBB method (1st results)

    Thanks for the feedback...I am going to try to answer all these questions..

    I am in Houston TX, the allege is mostly gone and the water is crystal clear for what that is worth. There are some very very slight traces of it on the walls of the deep end. I brush and comes right off the wall. I am going to clean the cartridges today to help clean the water a little more.

    Not running SWG
    The test kit now has a home in the utility room (air conditioned)...I will heed your advice.

    I am going to add another gallon of clorox tonight to get the clorine levels up a little more per your advise. The pool calculator says I need to replace water to lower the CYA, what do you suggest?

    So...where to go from here?

    Recheck your dimensions and gallons and post back....the 45k sounds like too much.

    Are you planning to use the SWG - if so the CYA is fine where it is.
    If you are not planning to use the SWG, what do you plan to chlorinate with?

    Well, you can lower the CYA level by replacing some water to get it to 50 or so, or you can try and manage with 70 and they CYA will slowly drift down.
    Just maintain the proper FC ratio (refer to the chart) for your CYA.

    what problems will I have with the running that high? Do I need to replace some water?

    It simply requires more bleach to reach shock level/targets. A higher CYA level means less FC lost to sunlight each day.

    I ran with 70 my entire first summer when I found TFP. It's doable. It's up to you

    Re: Starting BBB method (1st results)

    pH is up 7.3
    Clorine was at zero added bleach
    CYA is 60, I am wondering if I done the test correctly yesterday since it dropped so much...

    You need to do an overnight FC loss test - see if your FC is holding and take the sunlight out of the equasion. Instructions are in Pool School.

    Well this stinks FC is at 3.5 this morning from 6 last night Do I have to shock or can I try to control the problem? Will it eventually go away or get worse.

    If you lost more than 1 ppm overnight (which you did), you need to shock. If you don't, it will get worse. Make sure you're familiar with How to Shock Your Pool.

    At what level is it safe to swim while shocking the pool?

    The mods should be along to weigh in with a more expert opinion, but I don't swim when I'm shocking. I finish shocking (until overnight loss is 1 ppm or less and CC is 0.5 ppm or less) and then give the chlorine one day to burn off some in the sun. If I'm done shocking and FC is anything less than shock level (and I can clearly see the bottom of the deep end), the pool is open.

    I agree with loughps, you shouldn't swim while shocking.
