I have a 3 1/2 year old in-ground liner salt pool with the liner manufactured by GLI pool products. I have followed TFP religiously and was told by GLI this is not covered under warranty because it is due to “excessive chlorine”. My ph is maintained between 7.6-7.7, CYA 70, chlorine 3-5, Alkalinity 70-80, CH225. I think their response is lousy, but I would be curious on any TFP community thoughts.

I bet when you drain for closing, you'll notice the whole wall is somewhat faded below the waterline. It's from UV. I'm starting to see it after 2 seasons on the back wall that takes full sun everyday. The front wall shades itself after lunch and is the original color.

They are clearly trying to get out of honoring the warranty, as most companies do (successfully) with most products.

On another note, your 3-5 FC leaves you zero wiggle room for a particularly high UV day, equipment hiccups or a big storm. I'm at 7 or 8 times this season now that I caught the swg off for 12 hours for low salt when it ran its self check within an hour or two of a big storm. The twice a day test has to line up just so for that to happen, but given a season, it can happen a few times. Or an afternoon power outage that nobody's home for. Anywho, with CYA buffering the FC, slam FC is less harsh than tap water with 0 CYA and 1ppm FC. And it may have up to *4* FC. :shock:. Yet they wouldn't void your warranty for tap water because they dont understand how it works. :roll:

I run a 10FC and step in it drifts into the teens. I have a 2+ day buffer at all times where I'm covered for whatever the universe wants to throw my way. #teamrunhot.
 
Probably due to a cleaner grinding away at that location.

If it was chemistry, it would be faded everywhere.

If it was the sun/UV, it would be more extensive.

Watch the cleaner and you will probably see it grinding away at that location.
 
Notice how this Polaris gets stuck in the corner?

This can happen as a Polaris climbs the walls and get stuck and the front wheel continues to spin and it wears off the liner pattern.

In my opinion, this is clearly what is happening.

The corner is where the most fading is because that is where the Polaris gets stuck and the rubber wheel spins and wears off the liner pattern.

In my opinion, it is not chemistry.

I believe JamesW's diagnosis is ON THE MONEY. I couldn't figure out the excess pattern loss in the corner but he explains it perfectly.

Solution is to cut your losses and get a new cleaner.
 
James, I just got a Nautilus CC pool cleaner about a month ago. Problem existed long before I got the robot. Before that I used Pool Master handheld vacuum.
This thing is a mystery to me. One thing I might add, my pool is 14 x 28 deep end is 54”. My pool builder only installed 2 returns (wish I would have known more and would have forced him to do at least 3). Anyways, that corner of the pool is where I struggle with getting good circulation. Maybe this has something to do with it. I sure do appreciate your input and suggestions
 
+1 on the cleaner. My robot gets stuck under the ladder and has worn a spot in the (2 year old) liner pattern that is very similar to yours, but in a more contained location.
