Are you keeping your Cl level at 25 all day, or are you letting it yo-yo up and down? It may very well take several days to get it all cleared up, so your best bet is to forget the clarifier and just add enough bleach to go back up to 25 ppm. If you can test and add more 2-3 times daily, that'll even help it clear up faster. Keep brushing daily, and keep your filter running 24/7 until it clears up. Be patient, and it will clear!
