Finally got the kit and after much rain this past week I did some tests. I had drained it about a foot and refilled (did this 3 times over the past couple of weeks waiting for the kit hoping to make a dent in the CYA without much luck). I first did the CYA test and it was right at 100 so I did the dilution test and it tested 40 x 2 = 80 so I redid the first test and it was at 100 again and ran out of reagent. The cl was at 0 so I added 12 gallons of bleach and it tested 22ppm Saturday night, I ran the pump all night. Last night it was at 10 ppm so I added 6 more gallons and it went to 25ppm, this morning 13.5. This was the FC test, the CC test was 1 and .5. I tried the other tests last night, TA at 150, CH at 450 and pH at 7.8. The water is still very cloudy this morning and I have cleaned the cartridge twice. I actually can't see the drains but the water seems more blue-ish. I thought I would keep the Cl at 25 until the water cleared and wondered how long you thought that might take. We have been under drought condition water usage so I can't drain it completely yet, but thought in the mean time I would run the sprinklers off of the pool water and add new water to the pool as that drains out some of the water each week. With the chlorine level so high and the cloudiness no one wants to swim yet but we are anxious.... any advice would be greatly appreciated.
