I'm preparing to install a Hayward Aqua Rite Pro SWG. In reading through the instructions though, it says that the CYA needs to be at 80ppm. So instead of the usual 2 1/2 pounds my pool requires, I'll need to use 10 pounds of the stuff. 10 POUNDS?!?! Given the expense of CYA, how does maintaining 80ppm save me money over maintaining 20ppm with liquid chlorine? Also, does the higher CYA mean that there's more cyanide in the pool? How is it that the higher ppm doesn't pose a great exposure to cyanide?
Thanks for the help, I'm just trying to understand what exactly I'll be exposing my family to.
