I've got a question about shocking the pool with a Swg. I've been shocking the pool for a few days now using bleach and running the pump 24/7 with the SWG set where it normally is (to maintain 3ppm FC). The FC stopped falling Sat. night, and held steady untill Sun. night. Sun. night I cut off the SWG and left the pump running and the FC dropped from 21ppm to 17ppm so I'm still killing algea.
Is this the proper way to determine your through shocking?
