I cant maintain chlorine levels in my tub, no matter how much chlorine I add the free chlorine level doesn't seem to change. Tested my test strips in a glass of hot tub water and added some chlorine granules and strip showed the chlorine in there with no problem. Have now added loads of chlorine but no change, free chlorine still showing as zero!
Tub recently restarted after several weeks, dosed with non chlorine shock and chlorine, ph and alkilinity levels showing as ok
