Live in Summerville, SC. 5 kids,4 grands, 3 dogs, 1 cat. Some don't swim and some do. We put up a really big pool last summer. Above ground, vinyl, sand filter, 45x18x4.5. Took 3 weeks to prepare the site,5 days to fill it up. Love,Love Love this pool! We live in the country, kinda, and pine, oak, and other various pollinating greenery sure make pool maintainence a challenge.. Love this site and will appreciate any advice given.
