Chemistry good but water isn’t pretty

[BellaBuggy]

I use the TF-100 test kit. Current testing:

FC-6
CC-0
Ph-7.6
TA- 70
CYA-50

But the water looks pale turquoise instead of the deep blue we’ve always had in the past. It’s not a very inviting appearance.

We’ve been using the TFP method for years without issue, but I do most of the balancing and my husband does the cleaning. After opening this year I was out of town, and he put in chlorine himself. Instead of adjusting the pool math calculator to 12.5% strength, he accidentally used the default 6%, so he dramatically overdosed the pool. I’m wondering if that faded the liner and caused permanent damage? Is there any way to tell that without emptying? The liner near the top of the water line still looks dark blue.

Just trying to determine if we have some other problem to address, or if a new liner is in order next year.

My signature seems to have disappeared. We’ve got 29k gallon above ground pool, manually chlorinated.

Have you done an Overnight Chlorine Loss Test?
Does your fill water have iron in it?
Have you added any copper containing products?

Yes the overnight loss test last night showed zero loss. we’ve always used our hose water (city water) to fill and not had an issue before, but haven’t tested specifically for copper. The only thing I’ve added this year is stabilizer and liquid chlorine. Upon setup 8 years ago I added muriatic acid - possibly had to add it another year but I don’t remember for sure.

It’s rained overnight and all day today so the water does look a bit off from that, but it hasn’t been cloudy at all. Just not pretty.
