Can you run another set of current readings. How much liquid chlorine did you add and what percentage sodium hypochlorite was it? When did you add it? To clear a pool, you have to maintain shock level until you can go from sundown one evening until within one hour of sunrise the next day without losing more than 1ppm of chlorine AND you have no greater than 0.5ppm of CC. If you just shock the pool once in awhile, it won't clear the pool. Consistency and getting the chlorine high enough are key.
