We installed a new inground vinyl liner pol in fall Sept 2010, did not open (that is add salt, turn on the SWG), until Spring 2011. In less than 2 yrs, the liner has faded to the point of needing replacement.
It is a SWG pool, we watch chemistry fairly closely, but not religiously...no unusual chlorine ppm or other PH levels.
We also installed a solar blanket, which we use always at night and cloudy days, sometimes several days at a time.
We're still trying to figure out what went wrong?
The fading was all below the water line..so not sun/UV related don't think.
Does anyone have any science on the effect of high % use of solar blankets on SWG vinyl pool fading?
Could this entirely the cause of the accelerated fading or completely unrelated to blanket usage?
