Water was sparkling clean before last night when a huge dust storm came in. Had to backwash filter this am, vacuumed & tested water.
Here are my #'s
CYA was 80 yesterday
FC was only 3ppm this am, suspect flow was reduced causing SWG not to work overnight
Added liquid chlorine to bring FC to 7ppm, just wanted to bring FC up right away. Now after vacuuming the water is still very cloudy. Question is, should I bring FC to shock level now or just wait & see what happens??
