We're just getting our pool opened for the year and we had a lot of algae in the bottom of the pool. We used Aquachem and it's showing all levels are correct but the water is still pretty green and cloudy. (Link to picture below) It's a 24 foot round pool, roughly 13,000 gallons, our pH is at 7.6, FC is 1.5 and the test strips said this was all ok. We've used 3 lbs of powdered shock.
