I am a new pool owner and I'm having trouble with algae. I shocked the pool yesterday and the tests say the chlorine level is over what it should be, which I read was a good thing for killing algae. Yesterday the sides of the pool were slimy and now they fill clean like they should. I feel like I'm making some progress, but the pool is still green. Does anyone know how long it will take for pool to clear. And should I leave the filter on constantly until it clears? Thanks for any answers, I'm clueless but learning and this website really helps.
