    Tea bag/yellow to light brown stain.

    Hello, this will be my first post. These are my test results:
    FC 2.4
    TC 2.4
    PH 7.5
    AK 90
    CYA 60
    Calcium 300
    TDS 3300
    The water is clear.
    12,000 gallons.

    When opening the pool this spring we had pond water. Throughout the winter sometimes smelled like rotten eggs. The pool is 4' deep all one level and you could not see the bottom. The color then was green. I used bleach like I always do in the spring and changed the water to opaque color and cloudy. Added powder shock to the pool and after several days we had clear water. I then balanced the pool and shortly there after the yellow to light brown/tea bag stain showed up on the steps and in the corners. Eventually some on side walls.

    I used vitamin C to determine what to use and yes the Vitamin C worked. I used 1.75 lbs of Satin Free and it immediately got rid of the stain. Followed that with a half of a bottle of Metal Free. It's been about two weeks and now it has come back. Frustrated I took a sample in to check for metals. Results were .0002 on copper and big 0 on iron. That's the confusing part cause I am treating it as a metal stain but no metal is showing on the test. Getting ready to treat again with Stain Free followed by a full bottle this time of Metal Free.

    Bottom line is why has it returned and what else can be done? I don't wont this expense of continuing to treat it. I want the problem solved. Please Advise.

    Welcome to TFP!!!

    I am not too good at dealing with metal issues, but you may need to realize that a sequestrant is not a 1 time addition. It breaks down and you have to add more or the stains will return.

    Re: Tea bag/yellow to light brown stain.

    So would I use the Metal Free as maintenance to prevent the stain?
    Otherwise I would have to drain it and refill it?

    I don't think Metal Free is one of the sequestrants we recommend ... the article lists the ones with the ingredient we recommend.

    But, yes, you would have to keep adding it as a maintenance item ... how much and how often, I am not sure. But I think there is a way to test the level in the pool.

    Assuming you were filling with water with no metal in it, theoretically, after lifting the stain and then draining the water, the metal would be removed.

Sequestrants based on HEDP, phosphonic acid, or phosphonic acid derivatives are the most effective. Metal Free is not in this group and is noticeably less effective. It does work, just not nearly as well.

    Re: Tea bag/yellow to light brown stain.

    ok thanks. I just have not had this issue since it was installed in 08. Mainly frustrated as to why it didn't show up on the test yesterday and where did this metal issue come from?

    Re: Tea bag/yellow to light brown stain.

    Made a ton of phone calls today. Is there truth to your water not showing a reading for iron because its stuck to your wall as the stain?
    Last night I treated with Stain Free and scrubbed with vitamin C. Tonight it is crystal clear and my next action will be to hold down my chlorine, PH on the low side and AK at about 90. treat with a maitanance product. At first sign of the stain coming back I wont fight it. I will get rid of it and drain the pool. I had my tap water tested today and its clear of any metals.

    Then water replacement is your only course. Sequestrants never remove metals....only suspend them.

    Like you, I would try to find the source. Do you fill from a well? City Water? It seems that without knowing the source, it's hard to figure out what to do next.

    I am close to draining my pool

    I am close to draining my pool. I don't have time to monitor everything. I just discovered the cluster product last night and expect delivery by this weekend. Will report back later my results.

    Re: Tea bag/yellow to light brown stain.

    I changed out half of the water. While the level was down we cleaned with vitamin c and bar keepers friend. Filled back up on second day and the pool looks great! I have a c u later in the skimmer. Chlorine is 2. PH at 6.9, 80 on my ask and 60 on my cya. I am planing on keeping my chlorine and pH on the low side. I've backed off the swg to 20%. Let's keep our fingers crossed!!
