Throw the shock it around the edge of the pool AFTER backwash and rinse, wait 10 min then add the soda ash as instructed on the back. Kids can swim after 10min.
so backwash and rinse
then throw the shock it (soda ash cant be used on fibreglass they say)
and the alkilinity up ?
must that stay over night ?
also after backwash and rinse
can both be thrown same time
