I'm not that experienced in the pool field, we've had a above ground pool for a few years but last year we got a bigger one and I didn't want to take it down. This fall I just got so busy that I did not properly close my pool. We have a 21'x52'' intex ultra frame pool, it is salt water. In the fall after having my son this year I didn't close my pool properly, I unplugged the filter and the salt water pump and drained the pool below the filter lines. Stored the filter and pump in my shed, and didn't get around to adding any additional chemicals in my pool to winterize it. Also it was left uncovered, it does have a solar cover on it that kept alot of leaves and debris out of it but it wasn't perfect. My question is do I need to dump the whole pool and clean it and fill again, or could i shock it a few times, vacuum and clean and not have to dump all the water?
Thank you for any help!
