    In Dichlor-Bleach Hot Tub, are weekly chlorine shocks necessary?

    As part of weekly or monthly maintenance in a dichlor-then-bleach hot tub, are chlorine shocks necessary (12-13ppm FC, 30ppm CYA)? Or is it just in response to problems (cloudiness, odor, foaming, etc.)? Just getting over some hot tub rash, so I want to make sure I'm dotting every "i".

    Liquid Chlorine

    May I ask where everyone is buying their chlorine from? I know shelf life is important and making sure it is not old after reading threads. I am also wondering if more people just go for the bleach or the actual liquid chlorine? I am just starting to move myself to the TFP way of pool upkeep...

    So over the last week I had noticed that the deep end of my 16x32 pool had become a little murky, after testing it i realized the chlorine had gone now to almost nothing. I use a floater with three inch pucks to supply it. I refilled the floater and added a granular cal-hypo to try and quickly...
