    It's probably where the powdered chlorine sat on the liner. Not much you can do but brush it to make sure it's all dissolved and off the liner. You should either dissolve powdered chemicals before adding them or stick with liquid.

    i try to brush and vacuum it and still there i think the chemical bleach them out. The original liner is blue. Usually i walk around the pool and to shock it (i think that is the properly way right?) pool store tell me that

    how do you shock your above ground pool?

    I use bleach, but almost never shock my pool.

    The cost of replacing the liner varies quite a bit. An in-ground pool might cost around $3000, while an above ground will be significantly less.
