I am excited to be able to join this forum, as I recently purchased a home with a pool. This is my first entry into pool ownership, but I have been reading everything I can. Unfortunately my excitement has been dampening as we found an issue with significantly elevated levels of copper in the pool. We also have two little kids (under 4!) and the metals are very concerning to me. I have poured in 4 Liters of metal free, but still have copper (purple on the accucheck per Leslie's pools, which they stated was very high, but did not give me a #). I bought my own copper strips, which should be arriving tomorrow, so I can measure at home, and hopefully get a ppm measurement. Regardless, it was "purple" before 4L of metal free and after. I have also backwashed the DE filter following the metal free administration.
I would prefer to remove the copper, rather than sequester/chelate it, and from what I understand there are no products that definitively do that (I also purchased a CULator, which claims to and should be arriving in a few days). Ideally I would replace the water, but I have a vinyl liner, and don't know how much can be safely drained. It is a 22,000 gallon kidney shaped pool. Can we take out half the water, or is there signfiicant risk of the liner floating up with that load?
FYI: I believe the copper came from an old pool heater, that has since been bypassed, so hopefully there is no new copper coming into the water.
Are there any other options on how to remove the copper?
How much water can we remove?
Anyone have any advice...I would greatly appreciate it.
