We just opened our pool a few days ago. The water is pretty green and tests show that there is no CYA and only 1 ppm of chlorine in the pool. Alkilinity is also low. We shocked it but it didn't help clear up the algae since there is no CYA. I know that I need to increase the alkalinity with some baking soda. I need some advice, however, on how we can quickly raise the CYA before this pool turns into a swamp. According to the package instructions of the stabilizer, it will take 72 hours to increase the CYA. If I do nothing to this pool in 72 hours, I'm afraid the algae will get worse since it is so hot. Could I just shock with diclor until my CYA level gets to 30? I know that each 10 ppm increase with diclor adds 9 CYA so I could increase the CYA to 30 and increase my chlorine at the same time without having to add an enormous amount of diclor. Does this sound like It would work or is there a chance that it might fail since there would be no CYA in the water when the diclor shock is added?
