Run your pump/filter to get all the dead stuff out--a Cl of 60 ppm oughta do the trick! Remember that the bleach kills the algae and should turn the water blue/cloudy, but the filter gets the dead stuff out. If you'll test for Cl at night after the sun is off the pool, and test it again in the morning before the sun hits it, when there's 1 ppm or less cl loss, then you can let your Cl drift back down into normal ranges.
