No clue, but I'll set you up for the morning. I think you'll get asked:
- What chemicals were added to the pool at start up (sequestrants? clarifiers? etc)
- It sounds like there is an SWG involved, yes? Does the manufacturer sanction the use of an SWG?
- What does the manufacturer mean by "not allowed to use chlorine"? What are you supposed to use? An alternate sanitizer?
- What
exactly did you use for the chlorine you added? Was it plain bleach (which would be fine)? Did it have any additives (which would be bad). Or did you use "pool" chlorine from a pool or big-box store?
Clorox and others make "splash-less" varieties that have gooey additives. It could be that.
- Do the owners have kids? Could they have added something gooey? Kids are sticky. (Fact.) Have you questioned the owners about this? Any sort of suntan lotion disaster?
If all you did was pour in non-additive-havin' bleach, or chlorine made for a pool, then I don't see how you'd be liable. Surely the manufacturer is not selling pools that are "allergic" to chlorine!
Only other thing I can think of is some foreign substance is releasing from the vinyl. Introduced to the vinyl before, during or after the manufacturing process.
Others here will have better ideas tomorrow...
Edit: just looked at your pics. Yep, that's disgusting alright...
Can you read this and add your signature, as if this was your pool? You can take that down later. Can you post some test results? Both will be helpful to our experts.
We'd like to give you a few basic pointers of items that will help us, help you. From filling out a signature to posting test results.
