Ok, so I've been spending the past week trying to clear up my green pool. After falling for the pool store antics and reading these posts I've decided to become a TFPer. So now I'm wondering if I'm going about this the right way. I've got a 28000 gallon pool, vinyl liner, sand filter. I shocked it with 25lbs of Power Powder Plus because my calcium was low anyway. It's been almost 24 hours, I've backwashed a couple times and it's shown just a little improvement. Am I just being impatient? Did I add too much chlorine? Should I wait until my chlorine levels drop before adding more? My current readings are:
Also, with the Taylor test kit, how do you tell if FC/TC is above 6? The color match only goes up to 6ppm so basically, is there no way to tell if there a difference between say 10ppm and 40ppm? Thanks in advance for any help!!
