Hey Everybody, I’m in North West South Carolina. 27 foot diameter above ground pool. I struggle with not wanting to put chemicals in my pool because I have three young children. Through the swimming season I normally use pool salt, chlorine bleach, and a Remington ionizer. That has seemed to work great for the last four years. Closing and opening has been my biggest issues. I have pecan trees close by so covering is a MUST!!! I look forward to exchanging thoughts and ideas on now to make Spring to Fall a great time in the back yard.
