new pool owner here,
I have a sta-rite sand filter, older unit & a green pool curently trying to clear the algae, my question is,
should the sand be flowing out when I backwash?
I also know there is sand in the pool, when I brush in the shallow end I can see sand floating up with the algae & in the deep end I can feel the pile of sand with the brush but I can not see the bottom yet.
Where should I start looking?
