Do you need to put chlorine into a 10ft swimming pool?

Answer 1

It depends how much you use it. If you use it a lot then yes. If you don't use it a ton then you don't need it. however if it is outside then it needs chlorine no matter how much you use it.

Answer 2

You would still need to put chlorine in it because different people pee in it because it is a public pool. So you need to put chlorine in it to keep it clean.
