Just recently bought a house with a concrete pool .. owned a liner pool in the past never really had many issues with it. Paid a company to open my pool just they added some chemicals and left. For about a week pool was milky with tons of bubbles on top ran the filter 24/7 brought in a water test they gave mE some stuff to add so I did .. nothing worked called them back they suggested a Clear soc used that kinda did the job vacuum pool cloudly again repeat process this time I try this clarifier pool was pretty much clear had some leafs floating around added this pool clarifier had sooo much dirt on the bottem after 12 hours decided to vacuum to waste .... becomes cloudly again
