Dear Watermom,

I do know I need my own test kit and will get one immediately. I am not working currently and am trying to avoid any expense possible. I have read the Best Guess Chlorine Chart and am wondering if maintaining chlorine that high will be irritating to swimmers? Do you think I should dump about 8,000 gallons of water to get the CYA level down? That is what the pool store suggested.

Thanks,

Paul
