sorry Anna..i got that confused. i meant to say Stablizer 100 to raise the cya and that is bioguard product. i don't have the sheet...i forgot it at the pool store, called them on my way home and asked them to fax it to me as they were getting ready to close and i didn't have time to go back...well they did fax it, but it was blank sheets! i do remember them saying i need 9 lbs of cya, which i did buy Stablizer 100. i didn't buy anything else. i remembered it saying on here that you don't need to add hardness for a vinyl liner. my testing of the clorine tonight shows zero so i have added bleach again. do i need to raise to 50 by adding 9 lbs? and do i just put it all in front of the jets? thanks for helping me.
