I opened my pool this april and it was pretty green ,i followed "all" the instructions(did not used liquid chlorine,i used Cal hypo for the slam procces) in this forum and i had amazing results!! (crystal clear)
but there is something that worries me ,it is the CYA ,ive been testing the whole month and i have not readings at all ,i know its been cold here in GA but today it was pretty warm 70s and still not Cya readings (i can still see the dark dot when i do the test)
Any suggestions what should be the next step ? Some stabilizer ?
