Ok please see the attached photos. Slammed until I passed 2 consecutive OCLTs. Deep cleaned the filter added 120 pounds of sand to bring it up to full. (it is on the small side per my math pump has to run 22 hrs to turnover all 40k gallons) Tried to experiment with DE but never worked well for me. Brush walls biweekly vacuum weekly (mostly) All my numbers are good. (FC was low added 2 gallons of 10% to bump me back to 9ppm. Anyone have an idea why my pool is still cloudy?
