I am still alittle confused about the shock process. I have been going by the direction on the post about small pools. I have been putting in the 8 oz dichlor for the last four nights and making sure the FC is at 4 like the directions said, but the conversion chart says if the CYA level is 30 shock level is 12. So maybe that is why the water is still cloudy? Should I be raising the FC level?
