DPD Testing

[Waiawa]

I just got back from a vacation...9 days. Prior to leaving I had my FC at 16 accidentally, I was shooting for 12, but over shot!
I turned off my Chlorinator since it was at 16.
I was not too concerned since I knew it was going to rain hard for a couple of days, which it did.
I had to drain some water & vaccum before testing, and there were a bunch of leaves and bugs in the water.
The water looked a little cloudy, but not very much.

Got home last night, tested this morning and FC was at 0...CC was at .05 (I think, more on this later).
I added 50oz of LC and my FC came up to .5?? Added another 16oz FC came up to 1.5, added another 24oz FC came up to 3.0, added another 32oz and FC came up to 4.5.
A total of 122oz of LC added to get to FC 4.5 and CC at .5.

Now here's my question:
When testing with DPD, for CC, when I add R-0871 the water turns clear with one drop.
However, if I wait a few minutes it starts to turn pinkish red, and every time I add one drop it clears, but then turns pinkish red again after a few minutes.
It never gets darker or lighter, just the same shade of pinkish red.
Is this normal or do I have high CC?
I never noticed this, but then again I never waited after the water gets clear from the R-0871.
CYA = 30
CH = 125
PH = 7.8
TA = 90 (had to add Alkalinity Increaser)
Borates = 80
Temp 80

Water looks clearer now and normal, I'll check in the morning again to see where my FC is at.
Sorry for the long post, but I wanted to give as much info as possible, so y'all know where/what I did.

Thank you!

From my experience, your test sample will start to turn pink if you leave it sitting around long enough. When it first becomes clear, that's your result.

Your TA was under 50 ppm?

Take another CYA reading.

No, it was at 80, but now it's at 90 where I usually have it.

Take another CYA reading.

It will probably be lower due to heavy thunder storm now...it figures!
I'll be testing that and my FC tomorrow morning...after I drain my pool again!

That's what I was wondering about...so I guess my CC is correct at .5, thank you for verifying!

You will just frustrate yourself to micromanage TA. Just keep pH in the 7's. The TA is the least important value we monitor in TFPC.

Just to confirm, it is normal for the FC or CC test to turn pink again if you let it sit long enough. Both tests are meant to be completed and read immediately.

Yep mine does it too if I leave it long enough.

Now that's good to know!
My PH has been at 7.8 for the longest of time, I never had to manage it so far. I even made a bubbler just in case I had to increase it, but never used it.
