Hi there. This year I switched to Chlorine from Baquacil. I bought all new equipment that was never used with Baquacil. I have an inground pool, vinyl - 24K gallons (no heater). My pool gets direct sun most of the day. Lately it's been around 75 to 80 degrees. I have a Sta Rite System3 DE filter with a brand new Hayward pump and Hayword Chlorine feeder. I've been trying to balance the free Chlorine for 3 weeks and nothing is working. My Chlorine feeder is dissolving Azure 3" tablets and I have it turned up all the way. I also have a floating thingy in the pool that holds about 4 tablets. I also shocked with liquid Chlorine last night from the pool store - 2 gallons. I took a water sample to the pool store about 16 hours after shocking and still my free chlorine level is at 0.04 ppm. I have NO idea. They didn't know either at the pool store. They suggested I used Azure Sox All Plus instead - they recommended 3, 1lb bags. I still do not understand why my free Chlorine levels are low. The pool is crystal clear. The liquid shock did turn my pool green after putting it in but went back to clear over night. I read this could be due to metal in my pool but my recent pool tests show no Copper, Iron or Phosphates. I'm at a total loss here. Here's my latest test results:
Free Chlorine - 0.04 ppm
Total Chlorine - 2.17 ppm
Combine Chlorine - 2.13 ppm
pH - 7
Hardness - 97 ppm
Alkalinity - 15 ppm - I bought some stuff from the pool store to increase this
Cyanuric Acid - 66 ppm
Copper - 0 ppm
Iron - 0 ppm
Phosphate - 0 ppb
The pool store did say I should increase the hardness and I'm planning on doing that too, along with Alkalinity increaser and the powdered shock mentioned above. I figured with a chlorine feeder turned up all the way (brand new), a little bobber filled with tablets and shocking that I would have more free chlorine. Please help. I have no idea what is going on.
Thank you so much.
Steve
