We just purchased a foreclosure to rehab, and it has a great, but really nasty, pool. I've been working on it for about 2 weeks, and the family is now begging me to call in a pool company and just rip out the liner. So, I thought I would register here, tell my story, and see if I can get anywhere. Pool is about 35000 gallons, vinyl, 1 HP pump, sand filter. Under some trees, and I imagine the pool hasn't been used since last summer (if even then). No cover, so at least one winter full of junk. My undergrad degree is in Chemistry, so the treating doesn't intimidate me at all. I dumped a dozen boxes of borax in, brought the pH back to 7.6 with muriatic acid. I've kept the chlorine at 5-10 ppm for several days (using both bleach and some tri-chloro granules, but mostly bleach). TA is currently at 120. Now, to the leaves. I have both a leaf rake and one of the water-powered nets. I've FILLED a 90-gallon waste container full of leaves. Every time I think I have all the solids out, I pull out more. Not a bunch more, but honestly I haven't been able to see the bottom (not even shallow), so I can't really tell how much progress I've made and how much farther I have to go. Bottom line, I've kept the chemicals right, been shocking for 2 weeks and still green and murky. All advice welcome! Pics attached--the one of the water is fuzzy but the color of the water is accurate. Also, curious why the foam when I run the filter? I've read on this forum about metal in the water--this is municipal water from Memphis, reputedly some of the best in the world. Finally, a pic of my filter--anyone know if that cap comes off in order to replace the sand?
