white spot on bottom liner after shock?

[homer2cute]

Hi all

i shock 3 times last weeks and the pool finally clear i can see the bottom now. But the problem is i can see some big white spot (here and there) on my liner.. i think i shock the pool and the chemical is not dissolve and cause this problem, is this something i need to worry or need to change my liner soon? is there a way to fix this? liner only 3 years old and 30' above ground pool

thanks in advance,

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.

should i replace the liner? or is there a patch can be fix? although the liner only 3 years old and how much its cost to get professional install? average

Thanks advance,

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.
