I have an above ground vinyl pool. I recently had a bad algae bloom. I shocked the pool twice with Xtra blue bit didn't balance first cuz I didn't know how. The water is now nice and blue algae is dead but water is cloudy. Tried clarifier and didn't work. I have two stabilizer tablets in a floating thingy but when I test water free chlorine is 0 ppm but total chlorine is 5 ppm. Water still cloudy. What next?
