I didn't have time to do the overnight fc loss test last night. I'll do it tonight and see where I'm at......
reebok said:you need to lose 1ppm or less overnight. the only thing I really see is those samples are supposed to be taken 12-18" below the water.
JasonLion said:It also looked like the vial didn't have enough water in it. There is a layer at the top of the sample where the water isn't level, it has a curve to it, called the meniscus. The bottom of the meniscus should be at the 10 ml mark. From what I saw in the video, it looked like the top of the meniscus was at 10 ml.
That doesn't completely invalidate your results. Your actual FC level is probably a little higher than what you measured. A smaller sample will take fewer drops to change color. You still lost too much FC overnight to be completely done, but you are getting really close.

CYA lower? Do you mean higher? If your CYA was higher, you would get a better response from a higher chlorine level...
