Click the link on the test. Basically your testing your FC at dark and again in the morning to see how much you lose over night.
That's what I thought. I was just going to do that, use it as a rough estimate, and do a long SLAM to stay on the safe side. I dont know which link you mean, though.

But, now I'm wondering if I should just wait until payday when I can buy the needed test. I know what it is, I just can't remember the letters well enough to type them out. Begins with an "F" has a dash and then a "D" lol

I finally got the FAS/DPD test! Woot! Woot!

But, I'm not sure if I did it correctly, and am hoping you can let me know if I did something wrong.

FC-3
CC-0?

IT took 6 drops to change from pink to clear. When I added the R-003 it didnt turn pink, but it had a very faint pink "hue." Nothing like the bright pink after adding the powder. I had to hold it next to something white to be sure.

I added a couple drops of the R-0871 to see if it would go from the faint pink to clear, but it didnt.

Am I correct to think the CC is actually zero, or should I have kept adding more of the R-0871?

And if CC is zero, then I dont have to SLAM? Or should I do the overnight test? And if I do, does it matter how long after sundown I do the initial test?

Thank you so much for your help. I tell everyone I know about this site!

Did you water clear up? Sometimes heavy swimming stirs up a lot of dirt and can cloud the water. But hopefully the over night test will pass and you can move on :)
It looks perfectly clear during the day. At night, I can see a bit of cloudiness in front of the light. I tried to attach a pic, but it said my file was too large.

I am doing the overnight test tonight, bc it was so late last night. I was worried that it being so late past sundown it might alter the results. Im going to bring down my PH to 7.2 today just in case I dont pass, so I can start my SLAM tomorrow of needed.

I had ordered a CYA test bc I ran out awhile ago and I dont think I did it right anyway. After finding an excellent resource in another thread, I retested with more confidence. I lost the dot at 20, so I understand that means 30.

I had thought it was 50 and had my FC target set to the high end of that. Yikes.

Question, my pool is in direct sunlight by 9 a.m. and stays that way until sundown. I read that it could be necessary to raise CYA to 40 or 50? How would I know? And can I wait until after the SLAM so I can use less chlorine?

Thank you so much.
