Hi, I'm new to the forum. My pool was completed on 12/4/2010. It was designed as a salt water pool but we decided in the middle of construction to use Trichlor pucks. Now I realize that was a mistake. In 9 weeks my CYA level hit 100 ppm and I replaced half the water. For now I'm using 6% bleach and I plan to continue with bleach until it gets too hot. This summer I plan to install an intelichlor IC20 to go with the rest of the Pentair equipment and the Easytouch 4 controller. My concern is whether my 2.0 HP Whisperflo (single speed) is too powerful to generate chlorine. The Intelichlor manual says that the flow rate should be between 25 and 105 gpm. My PVC pipes are 2". I've tried to figure the flow rate by referring to the Whisperflo manual but it makes little sense to me. Any help would be appreciated.
