You didn't slam. You SL'ed. SLAM is Shock Level And Maintain. The key is the And Maintain. Anybody can give a pool a megadose of chlorine. It seldom does any good. You killed some algae, but you still left some to grow, and now they're coming back with a vengeance. And note-- if there's more than one strain of algae in there, you just killed off the weak one and the hardier strain is the one reproducing!

No, you must hit the algae hard and then kick it again and again and again to kill it all. Carefully read the SLAM instructions and follow them. It should only take a couple days to pass the Overnight Chlorine Loss Testif the water is already clear. My guess is that you really don't know how clear clear can be. Just follow our methods and see ;)
