I've been dosing 2 part for some time now and I'm just curious is it more effective to dose while the lights are on or while the lights are off ? I've been dosing after my lights go out . I do use a doser so my additives are dosed in a smaller amount multiple times a day . Calcium and alkalinity are dosed one hour apart . What do you guys think ?
