New liner fading...

[joshua5438]

Does this look normal for a liner that's eight months old? Below are my numbers....

FC - 6
CC - 0
PH - 7.6
TA - 120
CH - 125
CYA - 30

My FC was never above 10 this entire season. Only twice did it get above 7 and that was only for a few days. Not all sides of the pool look this way. This corner gets the most sun exposure. The side that gets less exposure do not appear to have a faded line. What are your thoughts? This is a GLI liner.

Some liners use sub-par dyes that tend to fade.

If your FC was maintained in range for your CYA, then a 7+ ppm would not cause a problem.
Low pH could also cause fading.

My PH was low the first week it was installed and then I lowered it to 7.0 about mid summer but had it back to 7.6 within a few days. I sent pics to my installer and he forwarded them to GLI. We will see if that goes anywhere.... When the water is up to the typical level you cannot tell that it has faded.
