Quarters in pool

[Lemonhead]

Will quarters in the bottom of a concrete pool cause any harm . I’m trying to clean a public pool and I’m afraid I don’t find them all . Serious question . Thanks guys

Unless they're on fresh plaster, they won't damage anything. Can you recruit local 10-year-olds to dive for them? First take a photo to show us your water clarity.
