I am a pool owner for 5 years. It is not easy to get all chemistry right, so I used two companies to maintain my pool. However, they just came once a week for a very short time, and I feel I still need to do work myself. After seeing algae growth last month, I stopped the service of the 2nd company and started to maintain myself. My experience was just to make chlorine and pH right. However, I mistakenly shocked my pool using dichlor. Then it became clear, but suddenly algae grew back since last Sunday. I am glad I found this site and realized my mistake. I have partially drained my pool to lower CYA to ~ 80, then SLAMing it with bleach. The water is blue now, and I am glad to see from here that it is safe to swim even with 30 ppm of FC. (I am not sure if my kids swam or not today). I have purchased my TFTestKits, and will do the overnight loss and CC test
