Need to understand 'shock'
We have a beautiful pool in central California. It is 25 x 50, negative edge. We have tried two pool care companies - neither worked out. I need to care for the pool myself. It has an ozone system, pebbletec, several water features, and a complicated plumbing system for the water features. We have the pool cleaner that runs around the pool with a bag, and clean that twice a day. It also has the popup sprayers in the bottom to move the dirt towards the drains. We clean the filters at least once a month.
We went to the local pool supply, bought a bunch of muriatic acid, new pole and deep water bag, brush. Asked about "shock" and they sold us Swimtrine Plus. It appears we need something else too. We want a nonchlorine shock treatment. What kind of shock treatment should I buy? Also, how often do you need to shock a pool that normally gets only family usage?
