just took the cover off and the water had a good amount of green alge. i put in alge killer and shocked the water. i also put the floater in with the chlorine tabs. the water turned a cloudy white color. the filter is new. the other levels are ok. at night with the pool light on there are small white particles in the water. do i just keep running the filter or is there a quicker way? i did put some clarifier in it. a friend told me to put the vacuume in the middle of the pool and keep filter running til its clear.
