Circular patches failing

[whatdidigetmyselfinto]

I have these circular patches on the side and bottom of our viynl pool and slowly the pool cleaner has lifted their edges.

These patches predate me. What could they be for?

They seem to be in a line pattern making me think of a strong chemical that was dropped and damaged the liner?

And finally : is that still the best approach going forward? Replace them with new patches?

That will be an interesting diving experiment

They appear to be just what you called them, "patches." Not uncommon for original liner material to be used as a patch over a leak/damage. May even be from the original installation. Perhaps the liner was dragged into the pool on installation or manufacturing defect.

So peel them off and psych again?

I noticed they have used a strong glue to apply them. Will I have to remove and reapply the patches? Or do you I will be able to apply some of the same glue to make them stick again? Patches themselves are fine just slowly peeling...

If you peel them, there is the possibility of tearing the liner, be gentle. You need a vinyl repair glue that can be used under water.

Oh right very good point!!
Maybe just add some that viynl repair glue and try to glue then back on.....

Don't remove the existing patches, that's asking for trouble. Patch over them with new bigger patches making sure to use plenty of glue all the way to the ends of the new patches. I don't know whether you can do this underwater or not.
