I have a new 37,000 gallon pool. I am using Sodium Dichlor as sanitizer with Nature 2 system. I was told to put 32 oz (2 lbs) in the skimmer twice a week which I did today. Afterwards the pool smelled strongly of chlorine and irritated my eyes a bit. I tested the pool for chlorine and it went off scale on high side. My question is how does the level of Chlorine (ppm) change through time (days 0-4) ? Would I be better off adding Dichlor every two days, or even daily to minimize "spikes" in chlorine levels?
