    Green tinge. Halp! I have numbers just new to this.

    I have some numbers and my pool stats are in my signature.
    I plan on running these tests again when I get home from work to make sure the numbers are in line.
    Mainly because I read the notice afterwards about going 18" deep. So that may throw these numbers off since I did not do that.

    Temp = 78

    FC = 15ppm
    CC = 0

    PH = 7.7

    TA = 210

    CH = 250

    CYA = 60ppm

    My pool is green and I cannot get it to go away. I sweep the bottom with a thick bag to get fine dirt. Some makes it through then the dispereses in the water and will settle to be dust again.
    It will be kinda better for a day then it will go back to how it was.

    Re: Green tinge. Halp! I have numbers just new to this.

    From looking at the photo I'm torn. It looks a little cloudy which tells me algae, but I can also see the pattern on the bottom very well, so,I think maybe metals in the water.

    How much chlorine have you been going through? Have you conducted an OCLT?

    I'm leaning more towards algae, so a SLAM is probably in order, but the OCLT would prove that.

    Re: Green tinge. Halp! I have numbers just new to this.

    I can perform a OCLT tonight if that is the best first step.

    I have had this issue constantly since about June. I have almost used the entire 5lb jug of KemTek.

    The water itself seems clear unless the stuff on the bottom is agitated.

    Do, the OCLT tonight - but re-reading your post and follow up I'm thinking the SLAM will be in order. Let us know about the OCLT tomorrow.

    And pick up some bleach or liquid chlorine on the way home. You may need quite a bit of it. At least 8.25% or better. Unless you have quite a bit of the HDX. Like 5 gallons or more.

    I backwashed and am now filling up the same level it was.

    Family member gave me some of this: Amazon.com: Aqua Chem 5-Pack Shock Xtra Blue for Swimming Pools, 5 Pounds: Patio, Lawn Garden

    Is that ok to use or should I just do bleach for shock?

    Also some more pictures now that the glare is off the pool.

    The 2nd to last picture is the outtake. The green stuff on top. I do not remember that being there, it does not come off easily either.

    I wouldn't use it. It's Dichlor which adds lots of CYA to the pool. You are already at 60 and really should do a partial drain/refill before starting a SLAM. You don't need any mnore CYA.

    That specific type of shock also has a copper compound. Metals in the pool = NOT GOOD.

    Re: Green tinge. Halp! I have numbers just new to this.

    Will do. I shall use bleach then.

    After backwashing, and also draining probably 1/5th of the pool and a fill.

    Here are my numbers for this evening.

    FC: 15
    CC: .5

    PH: 7.6

    TA: 230

    CH Turned Pink not red. Not sure if that matters.
    I finished the test anyways.

    CH: 375

    CYA: 33

    Remember, pH will read high anytime FC is above 10.

    Numbers for FC this morning!

    FC: 11

    CC: .5

    Surprisingly the bottom of the pool where the outtake pushes the water actually looks clearer than it did yesterday.

    With a 4ppm loss in FC overnight we havce proven that organics in the water are being oxidized by the chlorine. It is time to read the SALAM article well, stock up on chlorine (liquid only) and prepare to SALAM.

    You have a decision to make. A SLAM at 60 CYA is certainly possible, but needs a lot more chlorine than a SLAM at 30. So, take time and do a partial drain/refill to get the CYA down or just bite the bullet.

    At this point do not add chlorine until the FC goes below 10 so you can get an accurate pH reading and adjust to 7.2 with acid.

    With a SLAM the first few days set the tone. If you hit it hard and test and adjust back to shock level every hour or two it seems to get the SLAM going better. Witht he weekend in front of us that is the perfect time to work on the

    Re: Green tinge. Halp! I have numbers just new to this.

    Yeah I got my CYA down to 33 last night when I did a partial drain during backwash.

    Also my first set of numbers may not have been fully accurate since I did not take the test water from the right depth.

    When I get home I am guessing I will be below FC of 10. I will test PH and then get to SLAM probably starting tomorrow afternoon/evening.

    Do you have a way to vacuum the sediment?

    I have a way to get some of it, but there is always some that remains it seems.

    I picked up Amazon.com : Power Vac Pool Cleaner PV2100 26 Garden

    To use with my http://www.amazon.com/INTEX-Cleaning...wimming-Vacuum

    Hoping it catches the fine dust that I have not before.

    Going to use zip ties this time to fasten to the outlet, hopefully that will stop and debris from coming out fine gaps there.

    While better filtration will help get dead algae out of the water, we have proven you have a chemistry problem - not necessarily a filtration problem.

    The SALAM will fix most of your problems. Don't get distracted by the filtration at this point You need to kill what is in the water. Filtration is important, but it is really third in line after passing OCLT and CC .5 or below.

    Just checked my FC for the first time after 2 hours. It was 15.
    I boosted it back up.

    Here we go!
