hi all back again . have some green in pool

Don't need accuracy, just reliability to control the process of cleaning up your pool. However, if you run out of reagents and have to wait for delivery you won't know what's going on to any level of accuracy.

And, to answer one of your questions from one of the posts you wrote earlier, you do want the CC to be no greater than 0.5ppm.

This looks just like another thread....Is this a duplicate?

Follow up: Yes, it is a dup. I have closed the other thread. Please do not post the same problem as two different threads. We WILL see it.

Ok sorry so what about #s? Didnt think this should be in this thread that's why i asked in the other?

[Watermom]

How does the pool look? Your numbers look pretty good but you still do have some CC. As far as losing CYA, probably not. That test is so subjective that it is hard to get an exact number.

Pool looks great just concerned about the cya loss and 1 mod said looks like i just shocked but i didn't those #s was after a full day of sun been checking in morning and evening and only fc and cya show slight movement the cc is very little but its there

[Watermom]

See how much chlorine loss you have overnight. If you lose no more than 1 ppm of chlorine from sundown one evening until within 2 hours of sunrise the next day, and have no more than 0.5ppm of CC, then you are probably ok.

[airraid1999]

#s virtually same still have slight cc ?

[Watermom]

Hold the chlorine high one more day. If you still have no greater than 1ppm of chlorine loss overnight and if the CC is still no greater than 0.5 and if the water looks good, then let the chlorine drift down and keep it within the correct range based on your CYA.
