Cloudy pool? Stumped!

[Jbartels]

I am stumped! Since Thursday our pool has looked cloudy and while we did get some rain and heavy winds earlier in the week I figured it would clear up by now. Here are things that I have done since Thursday.

1. Brushed every other day.
2. Backwashed (sand filter)
3. Added chlorine there was 0
4. Balanced the PH which was 8.0
5. Cleaned all skimmers daily (added sock also)

Here are my current test results and according to PoolMath I am still in range. My robot is broken so i am just brushing and picking the leaves as needed. Yes, I do see some pollen but not as bad as earlier in the week. Any thoughts on what I could be missing?

Ph - 7.6
Fc - 5
TA - 90
Cya - 55

Have you done an Overnight Chlorine Loss Test? You may have algae and you will need to do SLAM Process.
Since you pool has had zero chlorine for some days then that is how algae can start.

Thanks that was going to be my next item to start checking..

You need to have a FAS/DPD test for FC testing. Not sure what a TF-2005 is. Do you mean K-2005 which is a Taylor kit as is K-1000.
Also could you expand on what Hayward “stuff” you have as it is helpful to know what type of pump, filter, etc.

Thanks @HermanTX I just got back in town to a super green pool so I am starting the SLAM Process. I will see how it goes after a few days.

In the heat of summer, it is best if you can test and replace FC every 2-3 hours. Even every 2 hours help. Any more often is not necessary.

We got you. Take a picture of the current status so we can see progress.

It's raining in San Antonio but not heavy. I have actually started to pump out some water since my CYA is 90. Going to try to get my CYA down to 60 first, balance PH, then start the SLAM (chlorine). I have scrubbed and backwashed twice. Once last night and this morning. All skimmer baskets have been emptied multiple times just in case.

7/24 @ 7:30am
CYA - 90
PH - 8.0
FC - 6 (I threw in some chlorine last night just to raise chlorine levels)

Add 5ppm of chlorine per day until you start the SLAM. This will hold off algae growth.

Use Pool Math to figure out how much is 5ppm. Link-->PoolMath

Thanks I use Poolmath for all my items.

Great. Do not worry about CH or TA, those can be adjusted after the SLAM. Tell us when you start the SLAM and what your ending CYA tested at.

Just showing photo from last night after draining. This morning I filled it back up and started the SLAM.

CYA - 40
PH - Adjusted to 7.2
Started SLAM process - FC - 11.5 and moving to 16

Yes I have the FAS/DPD Test

When you have time between your testing you may wish to update your signature on the Test Kit. Since you have the FAS/DPD test then change your K-2005 to K-2006. The K-2006 is a K-2005 + FAS/DPD. This way others won't need to ask if you are using FAS/DPD to test FC.

Take a picture daily of your pool now that SLAM is in progress. It is easier to refer back a day or 2 to see improvement in your color if you have photos to compare.

Not bad for 24 hours. Still cloudy but continuing the SLAM until OCLT is met. I should have stocked up on liquid chlorine so having to run out to get some this morning.

AND CC < 1
AND pool water looks like this-->How Clear is TFP Clear?
