It took me almost 2 weeks to do the conversion. Most people get theirs done in around one week, I have a lot of trees and hence had a bunch of leaves in the bottom that did not help matters at all, the chlorine was being used up pretty fast with both the bac and organic material. I did start seeing positive results after 4 days of keeping my FC up around 15ppm, I checked it 2 or 3 times a day and tried to never let it get below 10ppm. My CC levels were up around 8 when I started and was wondering if they would ever go down at all. I just checked the CC this morning and its.2 after 5 kids in it yesterday for 5 hours :lol: I am still fighting leaves in the pool. Hey if I can get it done anyone can, trust me.
