I'm new to the forum and love it here. My pool supplier advised me that consistently using liquid bleach would ruin (fade) my new pool liner. They sell 10% gallons of bleach but just recommend them for occasional shock during an algae bloom. From what I've learned here, it just sounds like they want to keep selling me trichlor pucks at $90 a tub. :blah: So just to confirm, have other vinyl owners seen any issues in the quality ofthe liner using 6% bleach? Thanks!
