Hello - I've had a heck of a time last spring and this spring with opening my pool with cloudy water. I've already put in roughly 40 gallons of chlorine with no readings on the chemical indicator and no visible change in the cloudy water. The PH is around 6.8 and I am trying to raise it with Borax and infusing with oxygen with the "sprinkler" system. The PH is also very sluggish and doesn't want to increase.

It is a vinyl liner pool that is about 9 years old with the original liner. I've never replaced the water and I think that it is about time. What is the best and safest way to replace the water in my pool to "start over" with fresh water?

Thanks, Ross
