Welcome to TFP! Unlike many, your chemistry parameters are near perfect to begin your SLAM. Your gonna need some regular non-smell good, non splashless, non germicidal plain old walmart brand 8.5% bleach. I would start with 20 or so gallons. Pour in about 3 or 4 gallons of bleach, wait about 30 minutes and test your FC. This should raise your FC to 12 or so. Test your free chlorine as often as possible and bring your FC back up to 12. Keep doing this until your CC are less than 0.5, your pass the OCLT and you water is crystal clear. Remember to brush your pool during the SLAM and keep your filter running 24/7. Be patience with the process and you won't regret switching to the TFP method!
