Well I went and had the water tested I had to add 8 pounds of balance and 4 ounces of clarifier and it's looking beautiful however we are getting serious rain here again in NY so it won't last long. The pool was put in our yard 2009. It's an inground vinyl liner. It is rectangle 12x24 and approximately 13,000 gallons. Now I face a new problem there's water behind my liner. This is the third time. We are getting a lot of rain though. We got over 4 inches in one day. I've looked for a video of how to get it out but can't find how to actually get behind the liner. The pool company charges 200 every time they are here and literally it takes them 5 minutes. Anyone know where to find a video do we can do it ourselves ?
