With a CYA of 95, I definitely would NOT use the pucks--they're what got your CYA so high in the first place. I also would steer clear of the powdered shock--dichlor is going to raise your CYA, which is already high, and cal-hypo will raise your calcium, which is also already high. If you have a vinyl lined pool I wouldn't over shock with bleach to keep from bleaching your liner, but if it's concrete, then it wouldn't hurt to go a little overboard with the bleach. Keep hammering it with the bleach--something in there is consuming it! It may take a good bit of bleach to get it cleared up, but your other levels are really too high to use anything else.......
