    Shock level and when to SLAM?

    My SWG was off for the winter. Last week, my FC level had dropped to 0.5 or 0. I noticed some color in the corners and hoped it was pollen, so I raised the FC to around 10 bc that was all the dichlor I had. finally did a filter clean today and color is back in corners. Think I need to SLAM, but...

    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".

    Using Shock as a Chlorinator? Could I use In The Swim Sodium Di-Chlor Chlorine Granular Pool Shock as an everyday chlorinator? If so, how can I formulate PPM for each ounce? Thank you all.

We have an automatic cover so it’s usually covered unless in use, and it’s used probably every other day. This is...

    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...

    Non-Chlorine or Chlorine Shock

    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...
