    Stain

    This stain started two years ago when we started using an intex SWG. It started just below the water line and went down about a foot the first year. This is after another year. I have looked at everything about stains, but haven't seen one just like this. Without water in the pool, I can't test for metals. Could it be copper or iron? From the SWG? My chemistry last year ran about right. I didn't have a way to test for metals.

    Re: Stain

    Test the water you filled the pool with. Alternately, did you ever add cheap algaecides in the pool that may have contained copper?

    What were your test results and what tester were you using?

    Is that black stuff still sitting in the pool or have you drained and refilled?

    Filled the pool with the same water we have used for the last sixteen years. Any good home test for metals?
    I really hate taking this to the pool store.

    Re: Stain

    The test for metals is kinda pricey so it actually IS the one test we ask you to take to a pool store. Do you ever get rust stains in the toilets? Or see water discoloration on your cement drive or any place your sprinkler puts down water? Those can be clues to iron in the water.

    Do you have city or well water?

    What were you testing with last year and what were your test results? How were you chlorinating?
