    Mustard Algae

    I’ve been SLAM’ing for close to a week - my second time doing so because I think I jumped the gun a day or two early last time I believe. I have passed the OCLT three mornings in a row. CC is virtually zero. But there is still a small amount of mustard algae every 12 hours or so, when I vacuum...

I only open the cover while using it but if i do not get time to swim I do let it breathe at least once a week in summer and once every 2 weeks in winter. However, I never shock my...

    Day3 of SLAM - Question?

    Hi Everyone, I opened my pool last week and got almost all of the visible organics out. I’m on Day 3 of the SLAM. My CYA was high 70, so I needed to get FC up to 28 according to the chart. I’m almost there - FC dropped a little bit after the first day, and I added some additional chlorine...

    Opened Pool - High CYA

    Hello Everyone, I opened my pool about a week ago and I'm dealing with a semi-cloudy pool (not bad, I can see main drain fine) and the smell of chloramines. I'm in the NE, I have loop lock cover and the pool water is usually disgusting when I open it - that's why I try to start early. I...

    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".

    Started the Summer with Algae - now we can’t get rid of a stinky smell in the water!

    First time poster here! Background info: we have a 20,000 gallon in the ground pool and have had it working well for 4 summers now. We have a sand filter and a nature 2 cartridge. 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...
