If it were my pool, I would drain about 1/2 the water and refill to get that CYA down. With it that high, your shock level is 25+ ppm of chlorine, and even when you get it clear, you have to maintain 8-15 ppm of Cl just to keep the algae blooms at bay. Unless you drop the CYA level to something more manageable, I don't know how you'll be able to keep the pool clear, let alone clean, all summer. I'm sure that the cloudiness is an impending algae bloom. After you added the cal-hypo, how high did your Chlorine level go? And are you able to sustain that? Did you add it through the skimmer, which would explain the cloudy water coming from the jet, or did you broadcast it into the pool?

Also, the only algaecide that we recommend on this forum is polyquat 60, and it's usually better as an algae preventative than it is in killing an active algae bloom.
