    Water looking greenish and cloudy

    Hi all
    I've been doing good all summer. Then last week we had a week of storms. Around Tuesday the bottom filled with leaves. On Saturday I notice a discolor coming from around the leaves. When I went to vacuumed up the leaves the whole pool got cloudy green and has stayed like that. I have left the filter going. I have added extra bleach to slam it. I added a clearer fluid yesterday and then thought maybe my ph was too high so added a ph dropper last night too. I then tried to slam the pool last night with double the bleach again. Still cloudy green

    These were my recordings before I added the ph dropper and the clearer liquid.
    My CYN was 40 before the rain. If anything it dropped a bit from the rain.
    Any help from anyone? I have used good bleach all summer and my numbers and water have been great.

    My clorine is good
    My ph was 7.8
    My TA was 130
    My Cyn was 40

    Re: Water looking greenish and cloudy

    If you are going to follow TFP methods you really need to do a little more reading back in the Pool School.

    You let leaves sit in the bottom of the pool for five days and I'm going to guess that that caused the FC to drop and algae has begun to grow. That was proven when you removed the leaves and stirred up the growing algae, hence green and cloudy.

    We do not "shock" our pools, we follow the SLAM Process when there is a problem.

    After the "shock", what is your FC other than "good"? What test kit are you using?

    You need to read the directions on SLAMing your pool in the How To section of Pool School and follow that procedure completely to the end.

    Re: Water looking greenish and cloudy

    I've read the TFP method and kept to it all summer. Sorry when I said "shock" the pool I just meant that I put extra amounts of bleach. So the good clorine reading only means that I have more bleach then normal to "slam" the pool. I couldn't get to the pool to vacuum it out until Saturday as we had none stop rain and a family emergency. I have the recommended kit from here and have been using it all summer. My FC has been between 2 to 4 every day. My FC reading is at 7 but only because I added double the bleach last night. I added 5 cups of bleach thinking I could try and "slam" the water
    Thank you

    As you have the test kit, you need to SLAM your pool.

    Backing up what tim5055 stated, we need hard numbers to determine whether the FC is really "good" since "good", in and of itself, is very subjective and imprecise.

    Leaves often contain biofilms and having a large quantity of them sit at the bottom of the pool for several days, especially at the warmer water temps of summer, can increase the rate of FC consumption thereby giving algae a foothold to begin growing. It sounds like a SLAM is in your future.

    I would also suggest reading the ABC's of Pool Water Chemistry.

    Please explain the slam as I guess I'm not understanding?

    Re: Water looking greenish and cloudy

    Ok I just looked at the slam directions on here and that is what I have done.

    Re: Water looking greenish and cloudy

    I have the recommended kit from here and have been using it all summer. My FC has been between 2 to 4 every day.
    Thanks for posting your FC levels. With a CYA of 40, you need to maintain FC in the range of 3 - 7 ppm. Since FC occasionally dropped to 2, this provides an opportunity for algae to take hold - and that's under normal conditions. Adding a pile of leaves to this equation will add more biofilm to the water and increase FC consumption which speeds up the process of algae growth. When dosing FC, I would target between 5 and 6 ppm to allow for normal FC loss to sunlight and lessen the likelihood of FC dropping below 3 ppm.

    As for the SLAM, you will need to kick the FC up to a target of 16 ppm and maintain that level as close as you can until the pool clears up.

    I put the amount of bleach to bring it up to 16 before work this morning. When I went home for lunch the water looks greener. And you can see a lot of brownish stuff settling on the bottom. I put more bleach in. Was that alright?

    Re: Water looking greenish and cloudy

    Did you test and find out that you needed to add more bleach and then use PoolMath to calculate how much to add to get from your test result back up to 16ppm?

    Not at lunch time. I panicked and poured more bleach in.
