I am in day 6 of trying to convert my pool from bacqa to chlorine. I also purchased the test kit from this site. I have used over 100 gallons of bleach so far and pool water is still green. At 7:30 pm tonight I added the amount of bleach I needed to bring up to 15ppm and 30 mins later I checked the level and it was down to 4ppm. I really don't understand how it could go that low so fast. I am hoping I am doing the test right. I put a scoop of the DPD powder in the cylinder with 10ml of pool water and swirl until it turns pink. I then put in 1 drop at a time and swirl the FAS/DPD until the water turns clear. When the water turns clear after you swirl and then turns pink again do you add more drops to make it stay clear? Hopefully I am doing everything right. I just want to see clear water again. Thanks for any help you can give.
