I had a Intex pool that I slammed and the liner bleached out/ faded badly and unevenly. It looked awful. I don't recall at what level I took the FC up to but it was not above 12 if I recall. Now I may need to slam my new Intex pool. The Mustard algae slam says to take it up to 42 until I pass a few test indicating the FC is no longer being reduced by the algae. I suspect 42 would completely bleach-out/fade my liner. Does anyone know what Intex says about the liner fade level when bleach is applied? Does anyone just know due to experience?
What level of FC causes the fade?

I cant directly answer your question, but I'm guessing it has to do with the FC/CYA relationship on the chart below. What is your CYA level? That will help people answer your question.

Depends on the liner quality and ink quality. Cheap liners with cheap ink can fade pretty fast compared to better quality liners.
I tried to put my numbers in my signature before but when I hit save it always says I used too many lines. Here are my current water chemistry numbers:
My pool has no shade. It can take direct sun all day and often does being I'm in Houston. Nothing like leaves, branches or bugs fall into the pool since there are no trees anywhere near it. It stays remarkably clean all of the time. My water chemistry is constant except for the FC which varies between 5.0 and 7.5 depending on sun exposure, play-time in the pool and or rain.
| FC: 7.5 in the morning and 5.0 after dusk |
| pH: 7.5 |
| TA: 70 |
| CH: 120 |
| CYA: 75 |
| Salt: 3,000 |
| Borate: 50 |
