I have been having smell issues with a pool cover for over 2 years and I am looking for suggestions on what could be the cause.
I have an Inground pool (Chlorine) in Oakland, CA. For safety reason, the pool is covered using a vinyl/polymer cover from Poolcover Inc.
After 5 years, our first pool cover started to have a very strong and acrid smell of burnt plastic on hot days. The sales rep told us it was because the sun had attacked the cover and it was time to change it. Which we did. But 12 months later, on the new cover the smell is back.
I think it is something with the cover.
The vendor thinks it is something with the water, but the water is clear (no trace of algae) and ph is between 7.2 and 7.4
I have tried multiple things: washed the cover (though I could wash only the top), start using Pool Perfect enzyme (suggestion from the the cover vendor), algicide, slam to no avail. The smell is still here.
Would anyone have any hypothesis on what could be causing that smell?
