the only reason i said still 100 for cya was that the test strips said that the ph and alkalinity affected the cya reading. also, where can i get test strips that give you a number higher that 10 for free chlorine? do i have to buy them at the pool store? i also have a dog who like to swim in the pool. is it safe for her to swim if she doesnt mind slightly green water or should i wait?

thanks
