If you don't follow the TFP method it won't work. Leave the chlorinator off get the CYA up to 30 and slam per the fc/cya ratio and keep the slam going until the OCLT proves good fc with not more then .5 CC and you've met all 3 criteria. Leave all the pool store junk out of the pool from now on going forward.
