Thank you! We are going to have torrential downpours tomorrow. Will this have any effect on the test?
Help?

It should not but you might as well wait to begin the Overnight Chlorine Loss Test after the rain passes.
Ok sounds good thank you. Did you happen to see my above post about the FC test I performed this afternoon? It was weird and looking for advice on that if you have time no rush.

If you leave the sample to sit after completing the test it will turn pink again. Do the test, count the result & move on
I went ahead and performed the OCLT due to the rain holding off. Below are the results:
Night Sample FC - 9
Morning Sample - FC - 8.4
Checked CC - Non Detect
Appears that the water is ok.

That’s a pass
How does the water look?
Is it cloudy or is there any visible algae?
If so proceed with
SLAM Process.
If not you may have dodged a bullet.
& you can do an overnight chlorine gain test to see if something is wonky with your swg.
It’s like the oclt only with the swg on.

woohoo! The water is nice and clear with no signs of visible algae. I’ll definitely do the overnight test for gain as well. I’ll report those findings soon! Appreciate the reply as well!How much time did it take to get that slight pink color? If I am not mistaken, the sample may turn back a little after a while but I will let others opine on the situation as well?
edit...nevermind, I see someone else replied. sorry
Overnight Gain test results below:
FC Night - 7.2
FC Morning - 9
It’s cloudy now and I’m not sure why all of the test look good if you look at my logs. I don’t mind slamming but finding the time to do it proficiently is my issues.
Any advice after I’ve past the Over night loss and gain test? It did come a torrential downpour here yesterday for around 8 or so hours.

Was your overnight gain test 12 hrs long & swg set to 100%?
If so your swg is supposed to be capable of approximately 4.4fc in that time.
You could raise to slam level & see if it clears up. Perhaps you caught it just in time & it won’t take too long. Nascent Algae can sometimes be masked/ kept at bay somewhat by an over sized swg but it will eventually overcome the swg’s ability.

Well I’m an idiot lol I didn’t set my SWG to 100%. It was at 50%. I can repeat the test this evening to know what I actually have.

I did my evening test and will do the FC again in the morning. The SWG is at 100%. Below are the results and this thing is getting depressing I really think something is wrong with my pool. My buddies pool doesn’t ever cloud up when it rains. Only thing I noticed is my salt is high and I’m afraid to exchange water and lower everything I’ve been working on. Should I call the PB and have them fix this?
FC - 11
CC - 0
PH - 7.4
TA - 80
CYA - 70
CH - 200
SALT - 4440
Temp - 62F

The most common cause of cloudiness is algae - this algae likely took a foothold when your fc was recently zilch or possibly before you increased cya if your fc ever got lower than minimum for your cya (your logs only go back to 10 days ago so hard to know).
salt being a little high won’t cause cloudiness. As you backwash & then replace that water the salt level will go down.
The rain has nothing to do with algae directly unless you were teetering on minimum & there’s a monsoon.
Based on your swg % & run time during your last chlorine gain test your results are roughly on par with what your swg should be producing. This means your swg is fine.
A Swg simply cannot overcome an algae problem. Algae will eventually win.
They’re not designed to, they’re designed to maintain fc levels under normal algae free conditions.
Eradicating algae requires the
SLAM Process.
The pool builder won’t fix your algae problem.
Your currently elevated fc levels may be keeping the algae at bay but that’s not enough to do the trick. You need to actually do the
SLAM Process.

I can slam for sure, but why did I pass an OCLT test? That’s what bothers me and there isn’t a green tint it’s blue blue but cloudy :-( logs go back to when I started testing my own water.

the oclt is not completely foolproof, the 1ppm leeway is to give margin for testing discrepancies & is only 1 indicator of algae free water-
the other two are
crystal clear water
How Clear is TFP Clear?
& no visible algae.
It seems as if you caught this very early & were just right on the verge so you still passed the oclt, now a day later you have cloudy water. My advice is not to wait for the visible algae to show up & just begin the
SLAM Process.
You could do another oclt if you wish to confirm but the answer to the problem is to slam.
Ok I will preform the SLAM. I appreciate the advice!
Started doing the Slam process yesterday and been keeping notes in my logs. Appears to be clearing slightly but slowly. FC was 25 this morning and I’ll check again after work. Temperatures are around freezing or just above so hopefully I retain my high FC for slamming. I stocked up on good bleach to be prepared and will continue to report back. I was worried about the freezing temperatures but I didn’t want to run my waterfall and increase the PH even though it would be slow, it’s my understanding I wouldn’t be able to confirm an accurate PH due to the high FC at this moment. No signs of algae visibly and non detect on CC.
