I just want to throw this one out there ...... I'd like to hear your opinions and responses. OK, say if one has a plaster pool , 10,000 gallons. The pool is in balance and is in mostly sun. If one keeps the CYA level around 30-50 ppm. On Friday I have added enough 12% liquid chlorine to bring the FC level to 4.0ppm . Will the pool survive one week until more chlorine can be added ? I'm not a big fan of tabs! I have been told they can ruin a heater as well as, they constantly add CYA to the pool . What do Pool service guys do if they only service once a week ? Opinions Please ! Thank you in advance .
