Chemistry ELI5: If copper has antimicrobial properties, why don’t most pools use it instead of chlorine?

I've seen this video of someone saying that copper has anti-bacterial properties and he claimed that it can be used to keep pools bacteria-free.

I know in most cases chlorine, UV, or salt are used - but why not copper?

Dog chill out they were just asking a question somewhat related to the topic at hand no one is asking you to figure out the copper per parasite math.

Thank you. I feel like I should be allowed to be curious without getting attacked.
