10 days later, pool water is still a clear green. I have done nothing besides run the pump 12 hours per day, and add some muratic acid following rain last week. Chlorine has naturally dropped off, and now we have warmer weather. Water temp has gone from 51 to 55. I have my Intellichlor set to 20% output, and I assume it will start producing with a few more 75 degree days and water temp hitting high 50's. But, I'm probably going to do an Ascorbic acid stain treatment over the weekend when the chlorine gets to 1 or lower. At least then I won't have to look at stains in addition to my perfectly clear green water.
Current test results:
pH 7.4
TA 80
CH 260
CYA 20
