This is my 3rd year owning and operating an 18ft above ground pool. This season after taking cover off no algae, but alot of dirt and debris, mulch etc. Vacuumed, back washed, vacuumed, back washed over and over. Bought an open kit added shock, algaecide and chlorine in that order. Mother told me I was supposed to balance water first then shock. Anyway, the water became very cloudy, so added 2oz of clarifier after 36 hours still cloudy, so added another 2 oz. still cloudy, will Pool Perfect work better, and should I keep adding this type of chemical or is there something else :?:
