hi. i'm beginning to doubt the chlorine production of my ichlor 30. so i'm running a test using my hot tub (400gals). according to the Pool Math calculator, if i run the SWG for 1 hour at 100%, the FC should raise by 12. if it only raised by 3 (25% effective), does this mean it's going bad? thanks all
