    Recovering Swamp-leftover stains

    Topic split from this thread by Moderator: http://www.troublefreepool.com/help-...ns-t12242.html

    I believe I have these same stains - there was MUCH leaf debris at the bottom of my pool this year. I had a late opening due to lack of funds, pool turned into a bog, leaves smelled horrid when I scooped them out, had insect larvae everywhere, etc.

    I ended up draining 95% of the water, threw 7 gallons of bleach in there, scrubbed everything down with Borax, and refilled with my garden hose.

    I did have to use some floc to get the water clean and get the last of the debris vacuumed out.

    Then I came to this site - after reading about pucks and commercial shock, CYA levels, and battles with pH, I'm not going to use pool supplies again unless I have to.

    So now I have 12 1 1/2 gallon jugs of bleach, 20 pounds of baking soda, and I forget how many pounds of Borax in my chemical supply cabinet.

    But I do have these stains - I rubbed a puck over them and noticed little difference, however.

    Just wondering what levels I need to raise the FC to, to rid the liner of the stains?

    I ran out of most of the testing agents in my liquid kit, and Walmart did not have any new kits, so I am stuck using a dipstick test. Less accurate, I know, but I have to work with that for now. I don't think my CYA will be very high since the pool is full of city water, but then again, I have no idea what they put in city water...so....

    Here's what the stick is telling me:

    CH - 100
    TC - 1
    FC - 0
    pH - 7.8
    TA - 120
    CYA - 40

    So....I got the hang of the pool calculator. Just wondering how to effectively get rid of the stains. Thanks!

    Re: HELP with Copper Stains

    I added 2 jugs of the bleach (6% bleach - 364 oz) and the dip stick is registering somewhere between 3 and 10 for FC.

    The pool calculator says that should put me around an FC of 8 starting from 0.

    Hopefully I will see the stains fade. Crossing my fingers.

    Hi Gina and welcome to TFP.

    Usually if the stain is organic, the puck will make the stain fade....

    After you refilled, you must have added a product that contained CYA, perhaps a powdered shock? Because city water doesn't contain CYA...

    Or perhaps the inconsistency is your test strips, which are very unreliable and inaccurate. I would recommend you invest in a good test kit, not the walmart kind, but one of the kits described in this article.

    Is your water clear now? Sounds like quite the cleanup process....

    Re: Recovering Swamp-leftover stains

    Oh yeah - duh...

    Once I refilled, I DID initially shock with 2 lbs of powder shock...and I added stabilizer to the skimmer. I still have about 8 lbs of granular shock left....and maybe 20 of the 3 inch pucks. I have had two puck floaters loaded with pucks floating around for the last 3 or 4 days too. I intend to remove them - they are old, stained, half broken, ugly, and a nuisance. Maybe I'll put what's left of those pucks onto the stains. I think the puck that is there is making a "little" bit of difference on the stain. It's hard to tell. I moved it to the darkest area this evening and will take a look in the morning.

    But you are right, between the shock and stabilizer, I have introduced CYA to the water. I don't intend to introduce any more.

    I started the BBB method yesterday. So far, I am quite pleased. After I raised the FC with the bleach, I "think" I noticed the stains getting lighter already after about 5 or 6 hours. I'll know for sure in the morning when I'm out there doing the overnight test.

    The water is VERY clear and the pool is squeaky clean.

    I wish I would have thought to take photos to show the difference, but I wasn't very proud of that stinky mess!

    I ran into pool newbies in the chemical aisle at Walmart today while I was searching for a liquid test kit and gave them the URL for this website! LOL! They had that "I don't understand how to use any of this stuff" look on their faces, while I am standing there with a cart full of BBB!
