"There is a good reason the pool store would show 9 cya. They want to sell you more!"quoted from waterbear.
waterbear you have the same idea i did. it looks like i only have enough test solution left to do the cya test one more time. (waiting on new solution in mail) tomorrow i will perform the cya test at home and check my results. hopefully there will be a higher cya level.from the amt of stabilizer i have added i think i should be in the 30-40 range.thanks for all the help.
