I decided to empty our green inground pool today and refill it ,i`m in the southern hemisphere and only having opened a pool once before i`m a bit lost about the best practice for starting up the sand filter after winter.
Yesterday I emptied the water through the filter to the drain, cleaned the pool and am left it overnight refilling . Is there anything I need to do to prepare the sand filter once it filled? ie backwashing first?
Before I start adding chemicals.
Thanks in advance
