The "stay-at-home" orders make me start looking for things to do in northern Ohio so I opened my inground pool. I cannot get the chlorine level above 0-1 ppm. I have a 17,500 gallon pool. I added 2 lbs of powdered shock to the pool. Most of it appeared to sink to the bottom. I ran my Pool Vac and it looked like a lot of the chlorine was vacuumed up and forced through my filter. (Lots of white clouds in the return ports.) 12 hours later - still no chlorine level.
I also filled my Rainbow 300 automatic chlorinator with 3" tabs and turned the valve to #6 (fully on). 12 hours later, still no noticable erosion of the tablets.
The water temp is 48. Is this too low to dissolve the powdered chlorine products?
Would it help if I predissolved the powdered shock in hot water? I am concerned that as soon as I add it to the pool the chlorine will precipitate out.
